Lop.ah Trojan

[neveryonas]

My pc is infected with trojan Lop.ah, found as litya.dll in c\windows
No Av programs are able to get rid of it, running windows normally. AVG pops up a message every 30 seconds. I have run AVG, AVG anti-spyware, and adaware in safe mode, and it still doesn't seem to get rid of it.
I have also run, Ewido, Fsecure on-line, and Trend on-line.

I have tried running on-line scans in safe mode, but for some reason, when I boot into safe mode, pc stops responding as soon as I enter IE or exporer.

I am out of ideas. Any suggestions.
Here is my Hijack this log:

Hi, thanks for the help. I did what you suggest, but unfortunatley no change. Do you think maybe AVG is malfunctioning?

Please try this (http://www.symantec.com/enterprise/security_response/writeup.jsp?docid=2006-092316-4153-99) fix from Symantec and let us know what happens.

Thanks so much, that seems to have done the trick!

If there is a report from the Symantec scanner, please post it along with a new HJT log just to make sure we got it all.

[neveryonas]

Hi,

There was no report when it finished.

Cheers,
Bonnie
