AvastSvc in AIS 5 crashing on full system scan

Avast Free Antivirus / Premium Security

I’m experiencing a crash of AvastSvc when doing a full system scan. It sounds similar to what’s described in this thread:
http://forum.avast.com/index.php?topic=54384.15

I’ve tried using procdump in a command window run as administrator, but so far haven’t gotten a dump.

The execution of procdump looks ok to me.
C:>procdump -e -ma -t avastsvc.exe c:\avastsvc.dmp

I’ve attached an xml save of the start and stop events from the system event log. I’d be happy to try and get a proper dump for you if you can give me some additional pointers.

Did you disable avast! self-defense first? (Settings / Troubleshooting) It might be necessary.
Also, some dumps (even though not that big/comprehensive) might have been created automatically in
c:\Documents and Settings\All Users\Alwil Software\Avast5\log

  • in the form of unpXXXXX.mdmp (X are some numbers) files.

Thanks for the pointer on the self protection. I’m uploading a dump file to the FTP /incoming dir right now.

If there are any unpXXXXX.mdmp files in your folder
C:\ProgramData\Alwil Software\Avast5\log

  • could you please upload them as well?

There was just one, and I’ve uploaded it: unp248282374.tmp.mdmp. I don’t think it was associated with these crashes, since there was only one, and the date was earlier than all my testing, but maybe it will help.

Igor, any update on this? I’d like to be able to have regular scheduled full system scans, but since it crashes the service, that would leave my system unprotected.

Do you have “Spysweeper” installed on your pc?
It was this program that was causing Avast to crash during a full system scan on my machine. I uninstalled Spysweeper and have had no problems doing a full system scan since.

See this thread…

Nope. Don’t have that. Thanks for the tip, though.

I was having the crash during a full scan, but only at night during a scheduled scan. I have since noticed it only happens when I use Utorrent overnight.

Are there any recent files called unpXXXXXXXX.mdmp (X are some numbers) in the folder
C:\Documents and Settings\All Users\Application Data\Alwil Software\Avast5\log ?
If yes (the timestamp of the file should correspond to the crash), please upload it/them to ftp://ftp.avast.com/incoming. Thanks.
