MSIL:Agent-U [Trj]

Every time I start internet explorer, I get an Avast pop-up that a Trojan Horse was blocked. The odd thing is, the file name of the file that gets moved to the chest is different every time. The original location is user\AppData\Local\Temp\Low.

I tried running the full scan, and it did find 3 files and rebooted, but I still get this message every time I start IE. Any suggestions for how to fix this?

Thanks.

The original location is user\AppData\Local\Temp\Low.

I have the same problem. Every time I right-click a file, I get pop-up from avast that my computer is infected with MSIL:Agent-U trojan. I have tried TFC, Malwarebytes, Spybot, and avast (all of them are up-to-date), but the problem remains.
