While running ad aware avast gives warning that I have a malware virus in system 32. The warning states "Win32-Malware-gen" has been found in "C:\windows\system323\x.264.exe"file.
avast cannot do anything as the file is said to be used by another process, I presume this is
ad aware. If turn avast off and run adaware, everything is fine and the above virus is not found.
Also if I just scan with avast, everything again is ok.
Can anyone tell me what is going on?

Can you submit the file to www.virustotal.com and check?
I'd rather more confident on avast detection than on ad-aware missdetection.

What does the above mean?

I have not used Ad-Aware for ages as it has not kept up with the times.

Get Malwarebytes Anti-Malware (MBAM) then update it then run a Quick scan and let it remove all it finds:
http://www.malwarebytes.org/mbam.php

Post its log here after it completes.

I have the same issue. Sign of "Win32:Malware-gen" has been found in "F:\WINDOWS\system32\x.264.exe" file. I've scanned with AdAware, Spybot, ThreatFire, SUPERAntiSpyware and Malwarebytes. All say the file is clean.

I Googled the file name and have seen all kinds of answers. From it being malware to it being something that Super® puts in. Super® is a video/audio conversion program by eRight Software. erightsoft.com/SUPER.html I tried submitting to virustotal but when I try to upload, the page refreshes and then says 0bytes uploaded. Installed their Virus Total Uploader and when I tried it that way I got the message "Error! Access to the specified file was denied!"

Attached screenshot is when I pull the properties of the file.

Cybersecurity is more of an attitude than anything else. Avast Evangelists.

Use NoScript, a limited user account and a virtual machine and be safe(r)!

I too have this result.

This is not the first time Avast has flagged it as infected. The search function on the forum cannot locate it but there is another thread on this from a few months back.

Avast acknowledged it was a false positive. The detection had something to do with the triple-layer-encryption or file packer or something like that.

Ask Polonus, DavidR, SPG Scott, Tech or one of the other helpful Avast Forum experts. They will be able to assist further.

The level of expertise required for a concise, yet thorough, explanation for this issue is unfortunately above my level.

Hopefully it will be fixed in the next VPS.

Would be helpful if there was perhaps an official comment from the Alwil staff too.

Best wishes,

Update:

I found the original thread: http://forum.avast.com/index.php?topic=37051.msg358846#msg358846

The suspect file was that time MOTA113.exe however I think x.264.exe is also related to S.U.P.E.R.

Otherwise I would be a little worried..................

Thanks for the replies. Looks like the last AVS update took care of the problem. Avast scans it now without flagging it.

Upon start-up, my Avast considers Ad Aware Professional  a Trojan Virus.  I had to go to the Avast Chest to retrieve the executable file and restore my Ad Aware.  Please advise how I may prevent this from happening in the future.  I'd like to keep both programs running at the same time if possible.
