Recently I have started to suspect that I have some kind of virus on my computer. There are 3 symptoms: Banners are being displayed on pages that doesn't use commercials, for instance when viewing screen-shots on Steam. It is only displayed after the rest of the page has been loaded and seems to be injected into it.

The whole page is replaced with a commercial with the option to skip the commercial.

The page is replaced with a search window claiming that the page could not be found.

I have tried to scan my computer with Antivir and Adaware but only found a couple of tracking cookies. I have run HijackThis but since this isn't really my area I haven't been able to discern what shouldn't be there except the line about zonealarm since I have uninstalled it.

Is there anyone out there who is able to see if there is anything suspicious in the log-file at the end or has suggestions regarding programs that might be better to find the virus than Antivir and Adaware?

Here is the whole (long) log:

This one looks very strange, while all others seem fine. Also, the name looks like just a bunch of random characters and Google can't find anything. Try to disable or delete this one.

Your answer lead my on the right path. I found a post on a forum written by someone with the same problem and that helped me the rest of the way. –  Skadlig Apr 19 '10 at 18:35
