Hello!
We are using multiple Avast 4.x licenses (15+) in our PCs and after the 4.8 update three of them shows very hard overall slowing.....
These are different DELL Optiplex machines (GX520,GX280..) with Win Xp SP2 and Zonalarm firewall.
when we are using MS Office applications together with CA-Clipper programs a simple task switch last 10-15 minutes, and sometimes an IE->Desktop switch last 5-8 minutes also...
I Set the:
self defense module= OFF
anti-rootkit=OFF
and nothing changes....
Any idea?
Thanks!
-
What Software do the other PCs use? Same Win XP SP2 and ZoneAlarm?
-
I'm having the same problem with my Dell Dimension E510 desktop running Windows XP. I updated to 4.8 (green box) last night and then tried to restart my system this morning. It has been locked on the "Windows is starting up..." screen for half an hour now. The mouse is still working (I can move the cursor around), but nothing else is happening. Any way to uninstall the avast update?
-
Are you referring to slowdowns and freezes or really a crash (or blue screen of death)?
Are there any files called <avast>\data\log\unpXXXX (where XXXX is a random number)?
If so, send them to vlk (at) avast (dot) com
They may contain more information about the problem (maybe a link to this thread).
Is the problem related to this one?

I can move my mouse, so the system hasn't crashed. However, I'm still not able to get past the "Windows is starting up..." screen. I even tried booting using "Last known good configuration" option in XP, but I'm still not able to get through the boot process.
-
Is there any useful information into Control Panel > Administrative Tools > Events, specially 'Errors'?
Do you have any other antivirus installed in your system? Did you have in the past?
Any other security programs that could interfere?

I haven't been able to fully boot, so I haven't been able to access the Control Panel. I just installed a new hard drive a month ago, and no other antivirus programs have ever been on it.

Maybe you can boot in Safe Mode and uninstall avast from there until we can further research what's going on...
-
I would have been happy if the slowdown was my only problem. All my apps started existing unexpectedly with the "Send report" dialog.
At first I had no idea what caused it, so I did a clean XP SP2 Pro install, with all 90 odd updates. Installed all my stock apps as usual, until installing Avast 4.8.
Everything worked great on the clean install till I installed Avast 4.8. I removed it, and smooth sailing since.
By the way, I also had that failing in one or other module in my event viewer, the one ending with a 5.
I really hope this gets resolved soon before my 30day Kaspersky runs out. ???

Error 5 is access denied, not enough rights.

I will give that a try...
ADDED:
I'm having the same problem with trying to boot in Safe Mode. I'm frozen during the boot process (selected Safe Mode with Command Prompt option).
-
BTW, I'm using Microsoft XP Home edition SP2...

avast is not loaded at Safe Mode.
Something else is messing your computer? Any new hardware device? Any 'old' one but that does not have the correct drivers installed (Control Panel > System > Hardware devices).

No, the only change is the avast 4.8 update. Since that's the only thing that has changed (hardware or software) since the issue appeared, it seems like that has to be the problem. It's too much of a coincidence that my slow boot process is very similar to others who are having 4.8 update issues...
-
Since that's the only thing that has changed (hardware or software) since the issue appeared, it seems like that has to be the problem.
Is there any old hardware without the drivers installed properly? Can you double check it?

I can't double check anything because my computer won't boot up.
I also just noticed on my Microsoft Vista laptop (which is the one I'm writing you on) that copying files from my flash drive to my laptop had become very slow. I just uninstalled avast 4.8 from my laptop, and everything now seems to be running OK again; files transfer at normal speed.
For me, at least, avast 4.8 appears to have been a snafu...
-
I was suffering with slow boot times and went as far as reinstalling Windows XP and going through all the processes of getting my PC back to health again only to find it was still having slow boots. I suspected maybe a imminent hard drive failure, but then thinking that Avast was updated and had started the slow boots around the same time I uninstalled Avast to see what the boot time was like after.
The result was from the 5ish min boot up that it was, to a "Normal" 15-30 sec boot.
I have been a user of Avast for some 5 years and have been very happy up till now. Don't get me wrong I'm not complaining about the trouble free previous 5 years, but there just seems to be a problem with this latest version.
At the moment I've no A/V installed, I wouldn't recommend running without, but it seems I can't recommend this Version of Avast.
Hope this can be fixed quick ???

IF I can ever get my desktop to complete the boot process (still not up after 30 minutes), I will be uninstalling avast 4.8. I hope I don't have to reformat my hard drive and reinstall XP to get to that point...

If you can't get it to boot into safe mode, I fear it's the only way.
Also, I wish to add to this that I'm not 100% sure that Avast has a problem as I still need to get some reboots under it's belt, but it seems too much of a coincidence that my system has returned to normal after getting rid of Avast.
I hope you can get your system sorted without resorting to a Format, bhuie >:(

Thanks, me too. I just installed a new hard drive after a crash about a month ago, so I've just barely gotten my configuration back to where it needed to be. I hate to start that process all over again...
-
It is a pain. Have you tried booting into safe mode? Sorry if you've already said :-[
-

Yeah, I've tried safe mode. It shows a sequence of drivers being loaded, then hangs up at the "Windows is starting up..." screen.
-
Fear a reinstall, or maybe a better option to try is a repair. Just don't repair on the first screen it's offered, do it from the second screen.
Your files and proggys should still be intact, well most....Not 100% but should be better to try 1st than a complete reinstall......Good luck with it.
Post back with how you get on >:(

Thanks Swordy, I'm off to attempt a repair of XP...

To be precises:
"Internal error has occurred in module aswar scan function failed!, function C0000005"
This has been corrected with today's VPS update, 080407-1
-
So your saying the slow/non boot issue has been fixed?
-
Reinstalled Avast, updated to latist version........Slow reboot back.
Guess the problem it fixed isn't the problem we are having ???

It was just a Virus Signature Update, not a Program Update :)
I suggest you go back to stable version 4.7 till all these issues are cleared up!

No that wasn't what I was saying, it related to the quoted text.

No it isn't wrong, I was quoting exactly what it fixed in the quote of my post.
The update fixed the error aswar scan function failed!, function C0000005, that Sauron posted and you quoted, nothing to do with any slow down.
-
Ah, okay. My bad.
Sorry to say I'm having to not use Avast from now till it's fixed ???

Well, I'm in the middle of XP REPAIR (have been working on it for several hours now) and XP has locked up again in the middle of the repair process. I can still move the mouse around, but nothing else is happening. I don't know what 4.8 did to my OS/CPU, but I'm not happy about it.
-
I very much doubt Avast would have done that......Sound like a more serious prob with your Windows Disk, or your Hardware ???

Unless the timing of a hardware failure is just amazingly coincidental, the Avast 4.8 update is the only change that's been made to my computer....
-
As Tech said - avast! is not loaded in safe mode. So, if you can't boot even into the safe mode, the problem is somewhere else.
-
What Software do the other PCs use? Same Win XP SP2 and ZoneAlarm?
Yes, same version of Win Xp Prof with Sp2, and latest Zonealarm, almost same applications(Office Xp, Novell client....etc.) and setup...
But different hardware, and these are important well monitored, and absolutly stable company's pcs, with Avast Professional licenses and flawless hardware...! :-\
1 piece Dell Optiplex GX280 with WinXp Prof. 5.1.2600 Sp2 build 2600.2562
512Mb ram, Family 15 Model 4 Stepping 1 Intel Cpu ~ 2793Mhz
2 piece Dell Optiplex GX520 with WinXp Prof. 5.1.2600 Sp2 build 2600.2562
1 Gb ram, Family 15 Model 4 Stepping 9 Intel Cpu ~3058Mhz
And the problem is the hard slowing, we havent any boot problem and if I set the Avast protection modules OFF the slowing is gone...... ???
-
If you work the avast providers one by one have you identified one provider that seems to be the cause of the excessive CPU utilization?

Slowdown, but very heavy (task switch between Excel<>IE =>4-5 min), if 2 IE page and 1 Excel and 1 Notepad file is already open the switch last near forever >:(
In the log dir I found only 1 outdated (2008.01.11) unpXXXX file (unp72974800.tmp.mdmp)!? I think that changes nothing.
-

Standard protection :P , but I know this so far....

Which is your Standard Shield sensitivity? High or Normal?
Some other program or driver is deeply conflicting...

Said the forum engine! :D :-X
"Which is your Standard Shield sensitivity? High or Normal?"
Custom: MS-DOS programs not scanned, custom skip list
"Some other program or driver is deeply conflicting..."
Only now? We are using Avast near 4 years.....
"Did you have any other antivirus in the past in this computer?"
Nope, only Avast.... 8)
"Other security program?"
ZoneAlarm firewall, and SpyBot S&D, but till now they not causing any problem.

You're right. I haven't noticed that.

Just thought I would add my experience to the list. I have two systems that will no longer boot after updating to 4.8. Same type of behavior -- mouse works fine but system appears hung. Task manager shows that the CPU usage is not maxed out and there is no network activity. Avast is about the only process active.
I can reboot in safe mode and remove Avast. This restores normal behavior of the system. Tried to reinstall 4.8 but the problem returned.
{edit} I should mention that both systems are running XP SP2. One is a Dell Dimension and the other is an IBM Thinkpad. The only firewall is the default Windows one.
-
No one has any idea, about what can I do with these two pc?
-
Here's a 'me too', sorry:
My weekly backup (around 38GB) took ~5h with 4.7.
After installing 4.8 (and excluding it's setup and data directories :( ), it now takes almost 8 hours!
So I counter checked, de-activated avast and ran the backup again: not even 4 hours.
Hmmm....
Hope somebody comes up with a solution. I was quite satisfied with avast for almost four years.
For now, I will have to disable online scanning during backup time, but if the next update doesn't
fix this we'll have to dump avast.
Regards!
-
Well I guess your weekly back-up probably also changes the file properties, like the last accessed date and or some other indication for your back-up program. So it may be that it opens the file for writing which may be causing avast to scan the file first.
You could pause the standard shield before the back-up so there is no interaction, rather than completely de-active avast. I usually run a scan before I do my weekly Drive Image back-up so if you did a similar thing then pausing the standard shield wouldn't be so bad. Though I have seen no change in my weekly drive image back-up as it obviously operates at a low level, it takes minutes rather than hours, but my data is much less than 38GB.
I back-up all volatile date files, the things that you don't want to lose, data files, like documents, spreadsheets, emails, email account details, registration keys, address book, favourites/bookmarks, downloaded files/programs, etc. the list goes on and on but if you don't want to lose it back it up. There are many back-up programs that can simplify this task and run it every day sometimes more frequently. avast doesn't seem to get in the way of that.
So if I do experience a serious crash at worst I lose 7 days worth of program installed (but should be able to re-install them from daily backups) and 1 days worth of volatile data.
I use a little program called mirror and I create a batch file to back-up those files I mentioned, it copies them to my second HDD and keeps the two locations synchronised so if I delete something from the source location it also deletes it from the destination.
-
I'm using the vanilla 'ntbackup.exe', run by little batch script from a scheduled task.
Disabling the standard shield is practically the same as disabling avast, because that's more
or less the only provider running.
BTW: How to disable standard shield only from a script?
But nonetheless, I'd still prefer not to disable anything, and have the old performance
back.
Reducing the amount of backed-up data is, of course, not an option.
Regards!
-
1. ntbackup.exe is the subject of a program update as it can't be fixed by excluding it, this is in hand and should be a beta release soon.
2. with the avast 4.8 self-defence module you can't. You would have to disable the self-defence module (before you ask, you can't do it from a script either). You would have to disable the self-defence module in Program Settings, Troubleshooting.
3. I think the disabling anything would in the case of the back-up be resolved.
-
Ah, yes, 'net stop "avast! Antivirus"' works only of course, if self-defense is also disabled.
Regards!
-
Your welcome.

Nice to hear! This will address the performance problems also?
Regards!
-
I have no idea if that will address the performance problems you refer to as it would only address the changes made by backup applications, which it would appear force avast to scan the file/s backed up.

I installed 4.8.1178, and everything (including the INI-Problem) seems to be back to normal :) !
Thanks a lot!

Glad to hear it and a belated welcome to the forums.

Ok, this is ridiculous.... >:(
God speed you Avast 4.8, welcome back Avast 4.7 with manual program update... ::)
No offense, but what a shameful stain dear Alwil team..... :'(

This post reminds me a little of the situation in which a proportion of the population is getting mugged. Someone comes up with an idea that will prevent that proportion of the population from being mugged. Trouble is ... it may cause a few teething troubles for some folks who are not being mugged.
The folks who are not being mugged are (I guess) pretty happy.
The folks experiencing the teething problems (even though they were not being mugged) are totally p*ssed off.
So gang .. what is better ... that the folks being mugged are not? Or is it more important that you do not suffer any temporary irritation and allow the folks being mugged to go on being mugged so that you stay comfortable?
Maybe this is not a community after all ... maybe it is a place full of freeloaders who only care about Number 1.
