Yeah, I finally tried the link you had, and it's malware, or possibly so. There is no 'security' directory, but the is a malware remover (somewhat useless), but at least I can run Hijack This!. Ad-awares' down to 'only' 70 bad things (including Cool Web Search), every time I do it.
I'm suspecting that what's happened is that the malware folks are 'organized'..if you're infected by one and miss it, the others are loaded as well, every time.
When I finally got CWS 'removed', it had gotten to the point that it created a randomly-named dll in System 32, which was loaded before you even get to the logon screen. No doubt it's still there, but my web habits must make for some pretty dull reading. My wife REFUSES to give up IE, because of Outlook (door #2 for hackers)..but that's a problem on 'my end'. The hackers may have gotten a leg up with Mozilla, it won't run...at all.
What I'm going to do is backup her data files only (nothing from Microsoft Word, Excel, or Access..@#$ing macros), format the partition, and start over.
It's a shame, she wants AOL, Realplayer, Napster (the legal one), Music Match, AIM, Limewire (daughter), and thinks these are 'good' programs..but, once again, that's on 'my' end..;) hey good luck.. but don't go to the first-mentioned site.

I wish I'd said that.. The Staircase Wit
