win32Malware-gen When Opening Firefox/IE

[mc_crater]

Over the last month or so have developed a problem in which avast picks up on some win32Malware-gen whenever I open either Firefox/Internet Explorer. I've attached a screenshot of an example of what is being blocked in avast.
Webshield also picks up a win32Malware-gen with a URL along the lines of http://ytimg.biz/MCheck/VersionRequest.ashx?codename ....

I also have Chrome which I use but have not encountered this problem

@mc_crater
Run zoek as you did before but use this script:

Code: [Select]

emptyclsid;
nmmhkkegccagdldgiimedpiccmgmieda;chr
ipconfig /flushdns >> %temp%\log.txt;b
autoclean;Wait for zoek to finish his work and post here fresh created zoek log report.


Zoek shall attempt to clean all that cache which may trigger avast. If problem stays, you may report files related to Windows Live Messanger and to Firefox ("D3C22d01" name) as FP. As they are not malware related.
