Firefox and sometimes IE opens random websites on its own , in new windows. I ran AVG scan and Anti Spyware as well as the Rootkit module. But even when it says my system is clean, the new windows come up in Firefox, about every two minutes. I noticed that Firefox doesn't even need to be running at first for this to occur. AVG resident shield does find sometimes a Trojan virus in some random dll (just popped up again, it's called Trojan Vundo) and I press heal or move to vault, but that didn't fix the problem. I also ran hikackthis and tried to delete whatever I deemed unnecessary or suspect from the registry, also deleting the associated files on the hard drive. But to no avail. My system is windows XP. Any other good free programs I can try to clean up my system? What about good cheap payware? AVG has been good until now but obviously it cannot cope with this new threat even in its most up-to-date form.

I've read so much here lately 1 2 3 about not browsing as an admin, decided to check it out and yepper, I surely was using an admin account. I've set up a non admin account, made a few other changes (described inside), hoping to find out from The Hive Mind if I am now safe enough to breathe easy(er). [more inside]

When checking out a gchat link from a friend to nbc.com, my firefox froze as "jew.wmv" tried to run (unsuccessfully) and a screaming chorus of "I'm looking at gay porno" came out of my computer. Does anybody know what the hell this is? [more inside]

Just like that, all Firefox bookmarks (several thousand) gone, homepage set back to this. No apparent viruses. Everything else seems fine. History is still there, and no suspicious websites there (JJill?). I have a back-up of bookmarks from many months ago, but would dearly like to get the later version back. Firefox 1.0 (I know, and today another scare.) Any thoughts?

Norton AV keeps finding java class files that that have viruses and trojans: byteverify, backdoor.Hacarmy, Js.Exception.Exploit. How do I keep them off my system?

I use both IE and firefox/firebird
