Title: Latest update crashed my computer
Post by: ululator on January 15, 2011, 08:59:49 PM
The most recent update to Avast crashed my computer.  I had to turn Avast completely off & run System Restore to get up & running again.  What the #@$&?!?!?

I have the free version of Avast 5.0.677.  Today (Jan. 15, 2011) I received a pop-up notification of an Avast update, which I installed.  Right after the required restart, I tried going online.  My computer froze, the display dimmed out, & I couldn’t even open Task Manager to kill the process.

After several panicky minutes, it cleared itself.  I then tried opening another program & everything froze & dimmed again.  Then the entire screen went black & I got a pop-up “security fail” warning.  Holy crap!

I was eventually able to restart my computer.  That’s when I shut off Avast & ran System Restore.

I’ve had the free version of Avast for several years & have been very happy with it… but no way am I going to risk another meltdown like that! 

Any idea what happened, & why?

Hello ululator: It would be helpful if you would state your OS and any other security software installed on your computer.
It's possible there is a download corruption.
Please uninstall Avast and do a 'Clean Install'

1>Download the latest official version of Avast, 5.1.889 Free AV:                    
http://files.avast.com/iavs5x/setup_av_free.exe  (http://files.avast.com/iavs5x/setup_av_free.exe) (English only) and save it to your HDD, somewhere you can find it again (if you didn't save your last download). Use that when you reinstall.
2> Download the Avast! Uninstall Utility, aswClear5 at: http://www.avast.com/uninstall-utility  (http://www.avast.com/uninstall-utility) and save it to your HDD (it has uninstall tools for both 4.8 and 5.0).
•   1. Now uninstall Avast! (using add remove programs, if you can't do that> start from the next step), reboot. When your system is up and running Reboot into ‘Safe Mode’
•   2. run the Avast! Uninstall Utility from safe mode separately, first for 4.8 if previously installed, your computer will reboot automatically, then reboot into ‘Safe Mode’, and run the tool again for 5.0. Again your computer will reboot into ‘Normal Mode’.
•   3. Install the latest version and reboot.

Please let us know if there are any further problems. :)

Thank you for responding to my questions so quickly.  Your instructions were clear & easy to follow.  I did as you recommended, & that seems to have solved my problem.

You’re right: I should have included additional info in my original message, but I was a bit too distraught when I wrote.  If it’s any help at this point, I have Vista Home Premium & AdAware 9.0.1.  In fact, it was while trying to open AdAware that I experienced the second crash, so I believe it was at least a partial source of conflict in yesterday’s problem.

However, your advice seems to have corrected whatever was wrong.  Thanks again!

I am having the same issue I think. I updated the avast with the program update tool it then froze at the end of the install. After rebooting I had the same issues with windows not responding at all. I ran the removal tool and did a clean install and still had the same issue with window freezing when i logged in. I have had avast for some time now and like it very much but currently it will not run on my system at all. I am running windows 7 64 bit system running on 8 gig or ram.

Did you follow the steps 'exactly' as laid out above in my initial response to ululator for a Clean Install?
Also, what other Security programs do you have installed now? Also in the past and how did you remove them?

I am running windows firewall and I did follow the steps exactly the problem started with the latest avast update that I installed yesterday. Oh and I have the Microsoft removal installed but nothing else ATM. The avast program hangs at the end of the install and I have to reset the computer due  to the fact that it is no longer responding.

I'd like to report yet another similar problem.

Windows 7 Ultimate (32 bit)
No other security software installed
Updated to 5.1.889 from 5.0.667 (free versions).
AvastSvc.exe is crashing.

(snippit from Event Viewer)
"Faulting application name: AvastSvc.exe, version: 5.1.889.0, time stamp: 0x4d2ebaae"
"Faulting module name: ntdll.dll, version: 6.1.7600.16559, time stamp: 0x4ba9b21e"
"Exception code: 0xc0000005"


It "seemed" to be working fine at first after I updated, until I rebooted. Then windows threw up an application error in avastsvc.exe. Waited till windows is fully booted, and the avast notification icon had a red x. Launched the user interface, it says nothing was running and gives me an option to fix the condition. It goes and tries to restart the service, which is a 50/50 shot that it will work. If it does, it crashes again with the application error as soon as you do anything that triggers avast to want to scan (opening a file, trying to access the internet, etc..). Rebooted, same thing. Downgraded back to 5.0.667, no problems at all.

And before you ask, no, I did not follow your instructions above, and with good reason. Regardless if it works that way or not, it still fails to address the issue that avast is "supposed" to allow updates, which have always worked just fine in the past for me (been using avast for years). That updating to this particular version has seemingly caused various crashing problems for a lot of people, there is obviously a problem somewhere. That doing a clean install fixes it for some seems to indicate that maybe the updater app is botching things. But given that according to some replies on these forums, not even a clean install fixes the crashes with this particular version (but no problems with older versions), that comes back to v5.1.889 itself being bugged somewhere.

Further, this workaround requires you to enter safemode. Problem is when you use a screen res higher then windows default and have icons on your desktop. Safemode uses default screen res, and icons that are outside the resolution boundary are relocated willy-nilly to empty areas of the safemode desktop, then when you shutdown and reboot back to your normal resolution, all your desktop icons are messed up because windows saved the icon positions from when you were in safemode. Happens to me everytime since the Win95 days. Just another inconvenience that I as a user have to be forced to deal with because the avast program isn't functioning as advertised.

Sorry to be blunt, but that's not my problem to have to deal with. I mean, thank you for the advice on how to hopefully get it working, but instead of work being put on the users, someone needs to focus on fixing the issue causing the need for users to have to do that to begin with. That one has to do things they shouldn't have to do and normally don't need to do just to get this particular version to work says all that needs to be said right there when you think about it. When have those conditions ever "not" been related to fundamental problems in the program requiring that extra TLC. Never that I can think of in my nearly 30 years of PC use.

Thanks, but I'll stick with 5.0.667 for now. Something is obviously wrong somewhere with regards to this new version, and avast downplaying this isn't going to get it fixed any quicker (though it does make long time users question their loyalty towards avast.)

@ goldenkey,

I have the Microsoft removal installed but nothing else
Are you referring to the removal tool that Windows Update offers every month?

You can first try an Avast Repair:
- Go to Control Panel > Add/Remove programs > Avast Antivirus.
- Scroll down and choose Repair function in the pop-up window.
- Reboot.

If the Avast Repair fails, you will need to uninstall Avast and do a clean install again with the instructions below.  Please note that if you had a prior version or product of Avast on this machine in the past, you will also need to uninstall that as well (see below).

I'd like to add one piece of information to the steps given above for the uninstall / clean install of Avast (last step):

1. Save a copy of newest version of Avast for the product you need and save it to your HDD:
Build 5.1.889 download files:
Free:  http://files.avast.com/iavs5x/setup_av_free.exe (http://files.avast.com/iavs5x/setup_av_free.exe)
Pro:    http://files.avast.com/iavs5x/setup_av_pro.exe (http://files.avast.com/iavs5x/setup_av_pro.exe)
AIS:    http://files.avast.com/iavs5x/setup_ais.exe (http://files.avast.com/iavs5x/setup_ais.exe)
2. Download the Avast Uninstall Utility http://www.avast.com/uninstall-utility (http://www.avast.com/uninstall-utility) and save it to your HDD (it has uninstall tools for all Avast versions and products).
3. Disconnect from the Internet at this time.
4. Go to Control Panel and uninstall Avast through Add/Remove Programs if possible and reboot.
5. If Step 4 fails, boot into Safe Mode (http://Safe Mode) (hit F8 repeatedly) and run the Avast Uninstall Tool.  Uninstall all previous products and versions of Avast you had on this machine at this time.
6. Reboot.
7. Install the newest version of Avast and reboot.
8. Get Internet access and register your copy or add the license key for Free, Pro, or AIS.
9. Update the Avast definitions.

If you continue to have problems, please report back and let us know what other security software do you currently have or had in the past on this machine including:
- Antivirus (AV)
- Firewall (FW)
- Trial versions of AV, FW and other security programs
- Other security software
And let us know how you removed the software.  Thank you.

@ Artlover,

Some users who have attempted to upgrade from a lower version to the higher version have had some difficulties and we have found that uninstalling and doing a clean install is the best solution.  Yes, there are sometimes minor bugs with every release with ANY software since everyone's system runs differently, however they do eventually get worked out.

If you feel more comfortable continuing to use v.677, by all mean do so as it will be supported for some time.  It is v.4.8 that will not be supported VERY shortly.

As for your concern of having to always go into Safe Mode for uninstalling, this is not true.  If you review my instructions above, you will note that the first way to uninstall is under #4, and this should not affect your machine.

I hope I have addressed your concerns.  Please let me know if I can be of any further assistance.  Thank you.  :)

I've also got serious problems after updating my free Avast. I'm writing this from my phone because I cant get past the XP (sp3) bootscreen after the update. Also I cant get to safemode either because it hangs on startup too. What to do?
Title: Re: Latest update crashed my computer
Post by: SafeSurf on January 17, 2011, 10:37:09 AM
I cant get to safemode either because it hangs on startup too.
Have you tried rebooting your machine (turn it off completely, then reboot), while tapping F8 to go into Safe Mode?  You should be able to do this. 

Has your machine been acting normally up until  you did the upgrade?

My comp has worked flawlessly until today. I cant get to safe mode. the loading hangs on giveio.sys which I think belongs to hw monitoring prog speedfan. After a bit of googling I found out this has happened to others after win update so maybe its not avast after all. I think xp updated yesterday.

The latest version hosed my computer too. Avast! Free w/ Windows7 Home Premium 64bit.
The first time I did a regular upgrade when prompted by Avast! which hosed my PC. Then I followed the instructions given in this forum using the Avast! uninstall tool and safe mode and did a clean install of Avast!. Didn't work either. None of my programs would open. Every time I tried to open a program I would get a "this program failed to open" error and numerous other errors. There is something seriously wrong with this version. I uninstalled Avast! again and replaced it with Microsoft Security Essentials instead. Everything is working fine now.

Hello Safe surf thanks for the help I did follow all your instructions and at the end of the install process the program still locked up my computer and forced me to do a hard reset. I then booted into safe mode and rand the avast repair and rebooted back in to normal where the program seemed to be working. I then turned the internet back on and rebooted again and my computer locked up when I logged in to my sign on. At this point I will have to wait for Avast to release a patch to fix the issue sense no amount of work on my part will get this to work on my computer.

Hi,

Recent update to avast crashed my fathers laptop running Vista.  The machine boots but the login screen never shows up.  The login screen background shows and the spinner mouse cursor is running with the "Please Wait" message which stays on forever.  He lives too far away for me to be there in person.  So, I have to debug/fix these problems over the phone and it is not easy.

I managed to get him to go to the safe mode with a hard reset and uninstall avast from within the safe mode.  This allowed him to reboot into normal mode and login to Vista normally.  I asked him to leave networking off on the laptop to be safe.

Once re-installing avast from within the normal mode, turning on the networking, and running the updates, he rebooted the machine only to have the same problem come back.   The machine hangs just before the login screen is shown with a "Please Wait" message and a spinner mouse cursor running forever.

So, he had to hard reset the machine to safe mode and uninstall avast yet again to make the laptop usable again.  But I am afraid to ask him to connect this machine to the network without any virus protection.

Anyone else have this same problem when using Vista premium 32-bit after upgrading avast on January 15, 2011?

I am going to try and use the aswClear program mentioned on this thread when I get home this evening.  If you had the same problem, did you mange to get it fixed by removing avast 4.8 and 5 using the aswClear program under safe mode?  I am simply trying to find out since it is a slow process to guide my father over the phone to do this.

I hope cleaning avast with aswClear under safe mode fixes the problem or a fixed version of avast gets released soon.

Thank you.

Same here.

Followed the steps....downloaded the removal tool, ran it, turned off all other security software except Windows Defender and Windows Firewall.

(You shouldn't have to totally expose your computer during an update should you?)

Anyway,  the only thing that saved me was a Clonezilla backup I did the night before.
System Restore failed.  System was totally hosed.

Been using Avast for some time and never had this happen before.

I have to agree that there is something seriously wrong with the current version. Not only did it stall Windows (7 - 64-bit) starting up, but if I did manage to start my computer, the RAM load shot up to almost 100% during bootup and stayed that way for some time or until I used a memory recovery tool. I tried unistalling, reinstalling, using the avast cleanup tool, etc, but nothing worked. I then tried Windows Live Essentials and had no problems with that. I have now put AVG Internet Security (Trial) on my PC and it's working great (much lower RAM usage than even when avast was working properly, ie. instead of about 75%, it's dropped to 35%). When I upgraded the program to the latest build on another PC in my home network, that refused to boot at all (I can't remember how I got it working again, but fortunately I did). Even though I've recently purchased a two-year, three PC licence, I'm now very tempted not to put avast back on my own PC again as everything is running better now than it has for quite a while and certainly since the latest version came out.

I have the same problem...what a mess and what a waste of time. My computer and the computers of my four children away at university all totally destroyed after letting the latest program upgrade execute. My XP Pro came up with no task bar and it killed my carbonite backup system and it killed my remote host software, also made connecting to the internet impossible. I had to uninstall all of those and uninstall Avast. I was able to use Windows uninstall...but my children with Vista, XP multimedia, Vista ultimate, and Windows 7 totally locked up no keyboard control and not able to pick any menus. Those I helped them through safemode boot and uninstalls. I have about 6 hours on the phone and here at home invested in getting rid of this junk. Understandably I hesitate to re-install anything from Avast...what is going on and when will it be fixed.

We will need more information to be able to help you:
- Which OS are you using? Is it up to date?
- What avast! version and VPS file (virus database) number?
- Do you use a firewall? Which one?
- Do you have any other antivirus installed in your system?  Did you have in the past?
- Any other security programs that could interfere?

Looks like i'm other guy that has issues with latest Avast! program update.

After update and reboot my system started failing, when clicking a shortcut to start something up i started getting messages that "... could not be started,... you might not have the needed permissions". When i then rebooted with a hard reset my computer no longer was able to start up, it hung on a black screen after the winXP welcome screen. To get my system going again i needed my backup tool Acronis to do a full restore to my latest system drive backup.

My system:

Windows XP Professional Version 2002 Service Pack 3
AMD ATHLON 64 x2 Dual Core 5600+ 2,81 GHz, 2,0GB RAM

It runs Avast! Free Antivirus 5.0.667 + defenitions 110117-1 without problem. Problem starts with latest Avast! Free Antivirus 5.0.889 program update.

Only security system running next to Avast on my computer is Online Armor 4.5.0.234 (as free version) with its Firewall + Webshield enabled and Program Gaurd + Keylogers disabled.

I'm no technical guy but new program version of Avast! overwrites something thats very essential with its update, perhaps you could look what new files it generates other then Avast! Free Antivirus 5.0.667.

Hope you guys can get it sorted, would realy miss Avast! when i could no longer run it. It always served me well!

Crashed my systems every time I ran v 5.1.8xx.
I use XP Pro sp3. I used the uninstall utility, I tried repair, I eventually had to remove it in safe mode, manually removed all registry keys related to ALWIL and avast.
Rebooted, removed the alwil folder from program directory.
Dug out my old 5.1.677, (unplugged from internet) and installed.
Went to settings and turned off the auto update. Rebooted.
rechecked settings (were defaulted back to auto update, so I disabled again)
plugged back into the internet, updated the virus definitions.

This is a serious problem for Avast. Many of my collegues use avast and we are all having the same problem simce 5.1.8xx updates. I'm ready to go back to Avira.

OMG I am distraught!  The latest updated crashed me too. I have the paid version of antivirus on Windows 7.  Did the update and now I get to the log in screen and it lets me log in but then it freezes.  The only way I can log in is in safe mode.  What's worse is this is on my roommates brand new laptop and he's livid. Needless to say I'm getting rid of Avast.

2. Download the latest avast! (http://www.avast.com/eng/programs.html) version and save it.
3. Uninstall avast from Control Panel (if possible). If, for any reason, you can't run it, try booting in Safe Mode (http://www.pchell.com/support/safemode.shtml) and doing it from there. Anyway, boot after that.
4. Run the avast! Uninstall Utility saved on 1. If, for any reason, you can't run it, try booting in Safe Mode (http://www.pchell.com/support/safemode.shtml) and doing it from there. Anyway, boot after you've run it.
5. Install avast! using the setup saved on 2. Boot.
6. Register your free copy or add the license key for Pro.
7. Check and post the results. If, for any reason, you did not solve, try doing the step 3 in Safe Mode anyway.

Same as all the others here. I installed this on my desktop a few days ago with no problems. XP SP3 Home. Last night I tried to update on my XP SP3 Pro lap top and the update installed fine, rebooted and the desktop did not want to load, No task bar, no start button, etc. I have exactly the same programs on both computers. I tried all the above suggestions and ended up uninstalling and running the removal tool in safe mode. Spent many hours on this.

Where can we safely download the 5.0.667 until this is fixed?

Guys, as there are many different posters here I try to keep this quite general...

As avast has a running behaviour shield now (also on 64bit systems)...
...please be sure to uninstall other behaviour blockers (like i.e. Threatfire, etc..)


Hope this info helps some of you...!
If this is not related to your specific problem, please start a new topic, as it's very hard to keep track on this crowded thread. Thanks..!

I think I've read enough on this forum to convince me to stick with ver 5.0.677.  My PC is a tool that I need every day and I can't spend hours trying to get it to work with uninstall / reinstall, etc.
 
Looks to me like this latest ver (.899) wasn't really ready to be released.

Don't loose sigh of the fact you are on a support forum and only those with problems come knocking on the door, the greatest majority aren't kicking in the door or boy would you notice it on the forums.

If your system isn't directly related to any of the outstanding issues running AOL software etc. then I would proceed.

I don't spend more than 20 minutes trying to resolve a problem on my system, if it is going to take anything over that I restore my last hard disk image, takes about 20 minutes.

If this system is a tool that you use every day then you need drive imaging software, take an exact image of your hard disk/partition every week, incremental backup images more often and you will never have to spend hours resolving computer problems for whatever reason.

####
With almost a month on beta testing and 5.1.864 was released, problems were found and pre-released builds were released up to 5.1.884 before after a time 5.1.889 was released as an official release, so no it wasn't released too soon, absolutely not.

Had you spent more time on the forums during this beta and pre-release phase you wouldn't be saying that. The problem is that with the multitude of users (140 million plus) on different OSes, different security software, different applications, you can't possible test for everything and you simply can't wait until you get zero errors as that day will never come.

No I didn't test it! If you read my post above I said I was sticking with .677 because it LOOKS to me like it wasn't ready to be released. In other words, too many people are having problems with the update where it's crashing their PCs.

Where can I download the old version for now? v5.0.677? I googled for this last night and the only sites that he it were crack sites and I won't go near those. The laptop I had the problem on is a spare computer which I don't use that often but I would still like to put the 5.0.677 back on it. Thankfully this computer I am using now which is my main computer is having no problems with this update.

Can I get the old one?

Just starting reading this forum. I too had major Window 7 problems after installing the upgrade. I have used Avast for over 5 years with no problems until now. The solution maybe with having Threatfire also running on your computer. My wife just got a new laptop also running Windows 7 64 bit and I installed Avast with no problems. But I forgot to install Threatfire. The main problem I had was programs not starting. I see that Avast now checks for suspecious(sp) file behavior the same as Threatfire and will not let the program start.Viola!That is probably causing the conflict. I guess I should uninstall Threatfire and try Avast again.

It can't only be ThreatFire, because I have that on both my system, both with Avast. The Laptop update is fine (W7 Ult 32), but my main computer couldn't start nearly any application, only TotalCommander still worked. Even the RunOnce at startup crashed. At least I was able to uninstall Avast for now and everything is working OK again. The crashing happened on a pretty new installation of W7 Ult 64. Both system have the same updates, but the laptop has a lot more stuff installed.

Do they roll updates out at different times for different countries? Just with the op being Jan 15th, mine auto updated last night (Jan 18th), it's a weird one this. Mine will boot to desktop and I have mouse, but if I try to execute anything, start bar or even the Avast main window the whole thing hangs, but I still have mouse movement. Wondering if CPU is hitting 100% and just slowing everything up? I can't get Task Manager to load, so no way for me to have a look.

I tried the Safe Mode, uninstall, downloaded the .EXE and re-install, and I still got the same exact issue, ahh well. So I have taken it off for the time being.

This is the first thing that has ever gone wrong in 8 years of use, so they haven't done too bad. Now get it fixed dammit ;D

It doesn't matter what the avast evangelists think.....the fact is the latest program update is flawed.
I've been running ThreatFire along side Avast for years so that is NOT the problem.
After being unable to open ANY program or application immediately following a reboot after the installation of the latest Avast PROGRAM update I was screwed with APPCRASHes.
I did two system restores on my Windows 7 x64 Home Premium machine, two uninstalls of Avast using the uninstall utility followed by fresh installs of the latest program update with the same results: utter destruction
Through a link somewhere in these forums I found a link to filehippo.com who provides older versions of Avast, one of which I am running right now.
Get the older version there (ie: the latest version PREVIOUS to the flawed release): http://filehippo.com/download_avast_antivirus/  Avast! Free Antivirus 5.0.677, which is latest working version and fully supported.
I will wait for another program update rather than screw around any more with suggestions that will not fix flawed code.

That said, I was a PAID Avast Pro user for years when I had my business but now am enjoying the generosity of Avast Free which also has served me well over this last one and a half years.

My 6 month old HP is now rendered useless after last update about 2 months ago. Froze and rebooted and was never able to get back on, even in safe mode. Tried dozens and dozens (and dozens) of times.

@ knitorious,

It would be helpful next time to open a new thread instead of posting in a 5 month old thread as you got lost here.

I need more information from you:

1.   What version of Avast did you install?   
2.   What product of Avast did you install?  Free, Pro, AIS?
3.   What other security software do you currently have or did you have in the past on this machine including:
- Antivirus (AV)
- Firewall (FW)
- Trial versions of AV, FW and other security programs.  Most new hP's come with trial AV's (N0rton or something else...please look into this as 2 AV's on the same machine will cause conflicts)
- Other security software
- If they were in the past, how did you remove them (the vendor's uninstaller's tool or  another way)?
4.   Are your MS Updates (if you have Windows) current?  Is your machine using SP1 or SP2?  If you have SP1, please update to SP2.

What produces the BSOD?  I noticed that you waited 2 months to ask for help on this matter.  Have you tried any scans in the meantime before your machine becoming useless?

If you have the original Windows Operating System disc and a CD or DVD reader insert the CD into the reader.  Boot the computer while holding down or continually tapping the F8 key.  I am not sure about Vista but I know that when you do this Windows 7 you get too a screen with a "Repair" option.  If you get this then strike the enter key with "Repair" highlighted.

Or you can follow the procedure to install "Last Know Good Version"

Hi,

Let's see if I can answer some of your questions.  It is almost impossible because I can't even turn my machine on so most of it is from memory (back from the January/February update) and I am only an intermediate computer user.  I was told by several people that in order to get my computer back to working order I would lose ALL the data (pictures, files, etc) on my machine so I have been using a secondary computer in the meantime so that is the reason I put it off all this time and only now decided to bite the bullet and look for a fix to the problem.

1.  I don't remember the exact version and there is no way of telling because I can't turn my computer on anymore.  The update was a popup in January/February if that is helpful
2.  The version was the free version
3.  I had been using the antivirus that came installed in the HP, which I *think* was Norton (?).  When it expired I decided to try the free trial of Avast before purchasing the full version
4.  I was using Windows 7.  As for SP1 or SP2 -- I don't recall and now have no way of knowing.  But I was good about installing the automatic updates when I'd get the popup.

QUESTION:  If I do the "Last Known Good Configuration" as the other user suggested (thank you Nesivos by the way), will I lose data? 
Title: Re: Latest update crashed my computer
Post by: knitorious on June 17, 2011, 10:25:16 PM
Hi,

Two things since my reply:

First I am using Windows 7 and not Vista, sorry about that.  And I read further into the instructions Nesivos gave for the last known good configuration and found the answer to my question about personal files remaining intact.  So I will give that a try tonight and see if that solves my problem <fingers crossed>  I will report back as to whether I am successful or not.  And thanks again for the tip.  Now if only I can find my original Windows CD!  ;)

For the record, this crash happened to my computer today after updating Avast 5.1.889 to version 6.0.1125 on my desktop computer running XP.  Computer kept re-booting itself, Windows would not load.  During one of the constant re-boots, I pressed F8 (several rapid times) and entered "safe mode" to Windows XP, then did a system restore to a time before Avast updated itself.  All is well now.

Same problem here (tried a fresh install on my friends Vista 32-bit laptop) ... Avast caused the laptop to black screen at the logon prompt ... Only fix is to uninstall in Safe Mode.

Seriously?!?!  This has been out in the wild for over a year and it's still an issue ?

One followup: AVG installed fine

I agree!  I started this topic over a year ago, & I can’t believe the issue is still not resolved.  Are you listening, Avast???

The only way I could get around the problem was by going into Avast’s settings & selecting MANUAL updates, instead of Automatic.  That seems to have done the trick… so far, anyway.

The fact that it started over a year ago (on a different program version 5.0.677 - update to Avast, 5.1.889) doesn't mean this is the same problem.

The problem is that people keep posting to this Old Topic instead of creating their own one giving information about their particular problem and avast version. Then that problem can be addressed tarter than raking over the ashes of this old topic.

Hi, I just downloaded the latest update for Avast and my computer will not work.  I can't get the safe mode to work. When I click on safe mode, it goes to the XP logo where it supposed to start, blank out and start again. That has never happened to my computer before.  Now I have to pay someone to get it working again. This is messed up.
Title: Re: Latest update crashed my computer
Post by: ululator on April 19, 2012, 06:32:38 PM
DavidR:
Yes, initially, it was version 5.0.677 whose update crashed my computer.  HOWEVER, I had the same problem with v. 5.1.889, v. 6.0.1289, etc… & presumably, this same problem is recurring with even later versions, judging by the volume of recent complaints.

The problem of updates crashing computers is clearly NOT limited to out-of-date versions, nor is it confined to just 1 or 2 individual users. 
It would appear that for whatever reason, Avast’s update process has an intrinsic flaw that has NOT been corrected over time or across program “improvements.”

Please don’t be so quick to judge or dismiss forum members who’ve written about it.

Using XP pro, service pack 3. Zone alarm firewall free without anti virus. Free version avast! After installing latest update, computer would get to start up, I signed in then nothing happened for 4hrs. I restarted, then I got the blue screen! Thought I got a nasty virus. Scanned with malwarebytes, found some adware, nothing major. Tried to restart, still the same problem. I reinstalled a back up of my computer, then everything was fine. Updated avast then tried to restart. I repeated the whole previous process because I didn't think avast! was the problem. 3rd time now, suspecting it may have been avast! update, I ran my restored computer through a few processes. Went on the internet etc. I updated avast! again (banging head on a wall) and yep, you guessed it. Computer crashes again. Now, however, I know it's the avastt! update. 3 days wasted and right in the middle of a photo project. Way to go avast! Didn't these years of the same complaints make a difference? I'm taking avast! Off my computer and never going to try this again.
