*dies laughing* Who would be the stupid fuck to program such a virus? The guy must wank to Tatu. :P
People, to generalize:
Pop-up Blockers:
http://download.com.com/3000-7786-10...ml?tag=lst-0-5 <<< Pop-Up Stopper Free Edition, it doesn't carry any spyware with itself and stops bugsome popups.
Spyware scanners:
http://download.com.com/3000-2144-10...ml?tag=lst-0-3 <<< Ad-Aware.
http://download.com.com/3000-2144-10...ml?tag=lst-0-4 <<< SpyBot (IMHO, better than Ad-Aware, has a simple interface and scans to the core, registry and robots).
Explorer Hijackers (that's what your page suddenly changing into another is called):
There are two solutions, the easy one and the computer registry one with which you don't want to mess unless you're big on moving REG key stuff (yes, I'm a Windows wuss.
).
The easy one is to change to another explorer.
I have Mozilla and while it has problems reading certain kind of code (*cough*Frontpage's*cough*MicrosoftSucks*cough*),
it's good.

Opera is also good, thought it has problems reading Javascript.

Back into spyware: it doesn't contribute to keep your computer clean if you download a lot of freeware whose creators assumedly get financial support if you install something that comes along the program you just downloaded (per example, I dunno, an online clock-synchronizer which in my experience is worth crap and synchronizes nothing). In these cases, it's better to buy your software instead of downloading it.
(Can I be in the back up team too? Pwetty pwease with a chewwy on top?)
