possible virus?

[wutamess]

I usually use Firefox but it doesn't do the trick on a couple of java based websites like ircspy.com or mydownloader.com.

Anyhow, I was looking for something on one of those sites and something installed on my machine. I can't find it anywhere and have updated and ran Mcafee Virus definitions as well as, Hi-Jack This, Spybot S&D, CWShredder, Ad-Aware and now running SpySweeper (hopefully I fixed it with Spy Sweeper).

Hijack this nothing was out of the ordinary in the registry.
The others found traces of things but nothing that's stopping my issue.

Issue: Every hour or so there's one Internet Explorer window on my taskbar. When I click on it it seems like it "virtually" comes/expands from systray but it doesn't expand onto the screen.

What's even more weird is that, each window (When it happens) is loaded with a different search engine everytime and that's it.
Teoma, google, altavista, gigablst, lycos, etc. Also there aren't multiple windows... just one (no matter how long I'm away from the computer).

I've searched google to the point I've reached the end of the internet. I'm pretty computer savvy and just can't find anything to get rid of it (assuming Spy Sweeper didn't do the trick). I've searched throughout the registry to no avail and delated some search keys from various places and even that didn't fix the issue.

Anyhow, does anyone have an idea or have ran across this before?
Any help would really be appreciated.
