Title: Avast keeps turning it's self off
Post by: moonharvey on May 09, 2010, 10:22:09 AM
I am having difficulty with the new Avast. I was running the older version and never had any problems with it. I just downloaded the newer version of the free avast today and have already noticed a problem. I look down after and hour or two and my avast has turned it's self off. I turn it back on and after a couple of hours it's off again. I have run a scan and everything is clean. I ran several different kinds and all good. What is the issue? I am running windows vista. I dont really know anything else about the laptop though so If I need to give you other info you will need to tell me where to find it. I was really happy with the older avast but now Im worried I made a mistake by upgrading to this version. Please help

hi tanith,

I take it you downloaded avast 5 free over the top of avast 4.8 free? This should have worked.

have you tried a repair of avast5? go to control panel...programs and features(add/remove programs),  and selected avast5, a repair option should appear.

if that doesnt help you may want to try to uninstall avast5, then run the removal tool, then download avast5 free again. Here is the removal tool.

if this doesnt help please come back and let us know, im sure others will be more than happy to give you a hand.

@ the OP: use the uninstall tool only if you can't uninstall "normally"...otherwise don't bother, as the "normal" uninstaller will clean your system better than the tool ;)

I always use the uninstaller after running the built-in uninstaller.
What seems to cause a lot of the reported uninstall problems is the failure to disable the Avast self-defense module first.

the self-defense module, at least on my system, has never been an issue for uninstalling. It's been one and it's still one problem when running system restore if needed.

I'm having the EXACT same problem.  I have tried uninstalling and reloading and that didn't fix it either.  I NEVER had the first problem with the older version.

Didimlr, did you try the removal tool, or just the standard uninstall?  You can find the link to the tool earlier in this thread.

Also, even though you are having the same problem as the original poster, it's better to start your own topic so that people don't get confused when they are trying to help.

Before you do the uninstall, it would be helpful to check the avast LOG folder (usually in "c:\documents and settings\all users\application data" in case of XP or "C:\programdata" in case of Vista/Win7) whether it contains any files named unp*.*. If it does, we'd be definitely interested in seeing these...

It is possible that there's a 3rd party application installed on your system which is taking the avast process down.

Thanks

Building upon that response from VLK, remember that the folders that he's asking you to look for are hidden by default.  If your computer is hiding them, you'll need to unhide them before you can access them.

Windows XP: (in a Windows Explorer Window) Tools > Folder Options, click View, then check "show hidden files and folders"

Windows Vista / 7: (in a Windows Explorer Window) ah heck... just click here: http://www.sevenforums.com/tutorials/394-hidden-files-folders-show-hide.html

Mine is doing this also, and I wish it would at least make a sound when it turns off!  Rather distressing to notice the slash through the icon and wonder how long it has been off.  Didn't see this as an option in the sound settings, though.

Do you have any of those unpXXXXXX.mdmp files in avast! log folder, as Vlk mentioned a few posts earlier?

avast4me25, what operating system do you use?
Title: Re: Avast keeps turning it's self off
Post by: avast4me25 on May 25, 2010, 12:26:19 AM
Windows XP SP3 home
Title: Re: Avast keeps turning it's self off
Post by: igor on May 25, 2010, 12:34:37 AM
Hmm, pity :(
If it were Vista or later, we might be able to extract the dumps from the Windows Error Reporting applet; I'm not 100% sure, but I think it's not possible on XP.

@ Igor and Vlk,

I tried this when I had the same problem, which I do not have now, and it did not work.  I have XP as well and know how to check for hidden files.  I also didn't get any Event Errors.

What did work for me on my machine was to do the following to resolve the problem:

-  Disable Avast prior to uninstalling
-  Uninstall the normal way (Control Panel > Add/Remove Programs)
-  Reboot
-  Clean the machine (Ccleaner works well)
-  Reboot in Safe Mode and use the Avast Uninstall Removal Tool, which removed MANY parts of Avast
-  Reboot
-  Reboot into Safe Mode again and check for remnants by Search All Files and Folders > Advanced Hidden Files (remove them only if you know what you're doing since parts can sometimes be left behind)
-  Reboot
-  Clean the machine and check for registry errors (Ccleaner works well)
-  Make sure with an on-demand software that the machine is malware-free
-  Defrag the machine prior to reinstalling Avast again
-  Install latest build of Avast, update definitions, and register product.

I've had no problems since following this procedure :)  I know this may seem tedious, but I had to do this on 2 XP's and so far it worked.

When I had a problem with avast! on my XP Pro system this tip helped a lot:
How to invoke memory dump creation?

Not sure if it works on XP Home though.

Thanks for all the help. I have been trying different things when I can. I have repaired the program like the first recommendation and we will see if that works.
To Vlk. I have been unable to display avast logs. I went to another site that told me how to show hidden files in Vista, which is what Im running, but nothing ever came up under Avast other than just the turn on program link. So I have no clue if I have a ump file in the log or not.

Post by: moonharvey on June 09, 2010, 11:11:46 AM
So the repair did not work, now trying the uninstall. Just one problem, I dont feel comfortable with the cleaner software, installing is fine but opening in safe mode, what if I have problems, how do I get out of it,Im really not a computer person and I cant even see the avast log files.  Im going to try for  now just reinstalling it, If I continue having the problem I will try it again using the cleaner/uninstall program. Let ya'll know.

Post by: Tarq57 on June 09, 2010, 01:42:17 PM
moonharvey, it might seem a bit of a mission to run the uninstall tool, but it's really fairly straightforward. But first, when you look for the dump file, rather than looking in the Avast GUI for it, try looking via windows explorer - pretty much the basis of the operating system.
Double click on "my computer", and a window will open, within that window you can navigate through the various folders and sub folders to find the one containing any dumps, if present.
So from the explorer window that opens, you'd then open "documents and settings". Then "all users" (or "users"). Then continue as the path posted by VLK points.

Post by: moonharvey on June 11, 2010, 01:11:09 PM
Well my Avast has shut it's self off twice in the last couple of days, which is better than the every couple of hours it was doing before, (It did stop a Trojan virus earlier tonight so glad it's staying on longer) I looked for the dumps/logs but still cant find them. I looked under windows explorer and no files. Im on vista for laptops so if anyone can walk me through the process step by step that would be great but some of the folders yall are telling me to look in I dont have (Like documents and settings). I will have to remove the newly downloaded Avast with the removal tool but I am really nervous about it since I dont know what I am doing and I cant even find logs and dump folders. I could really use step by step directions from someone using the same operating system. Any help or advice before I do this removal/cleaning tool would be appreciated.

I suggest an installation from scratch:

1. Download the latest version of avast! Uninstall Utility (http://www.avast.com/eng/avast-uninstall-utility.html) and save it.
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.

Okay, I'm having this same trouble, and it's after getting rid of a nasty little piece of malware called AV Security Suite. I think I got rid of it, but ever since then, which was this morning, Avast has been being shut off in the midst of my computer usage. If you have any ideas as to how to fix this, please let me know.

You might also want to check the system with spybot search and destroy ( http://www.safer-networking.org/en/spybotsd/index.html )
and superantispyware ( http://www.superantispyware.com/ ), the portable version is great.

You do not send the mini-dump file to the forum.  Please read here and where to send it:

Here is additional information on how to invoke a memory dump file:  http://support.avast.com/index.php?_m=knowledgebase&_a=viewarticle&kbarticleid=71 (http://support.avast.com/index.php?_m=knowledgebase&_a=viewarticle&kbarticleid=71).

Please help, the latest version of free Avast antivirus keeps stopping with errors. After restarting Avast, all works fine, until the next error.
I have tried repairing my install, and I use no other conflicting software. It is extra annpyoing, because it is hard to tell when avast stops working, and it just seems to happen randomly.

I find error logs and .dpm files in my Avast system directories. For instance the error log reads:

@ ajjeru,

Your post got lost in this very old thread.  Your last question was asking to send the dump file to the forum, which I instructed you on 10/06/10 was incorrect and gave you the information where to send it.  I will give it to you again:

- ZIP the file \windows\memory.dmp (try to name it uniquely) and upload it to the following ftp site: ftp.avast.com/incoming (note you don't have read access to the site, only write).
----------------------------------------------------------------------------------------------------------------
Any other posters wishing to post regarding a similar issue needs to open a new thread.  Thank you.
