Hey Niki, you are aware that
Norton Anti-Virus is notorious (pun intended) for being a "back-door" program? That basically means that certain viruses and trojans can actually come through into your computer via
Norton. Abandon it.
I personally use the
Free Spyware Adware Scanner and Remover. Although you need to pay $30 bucks for it to actually be useful (it's really not free; of course you won't have to pay if you don't mind scouting around manually and finding the infected files and deleting/fixing them), it will scan for viruses and even trojans (surprisingly, they're not in the name).
It's worked great for me for several months now. I personally feel
AVG is overrated and so is
Avast!.

Of course, if that doesn't float your boat, try PREVX-CSI (which you'll have to pay for IF you want it to do the automatic removal and fixing of infected files, just like the one posted above; it will scan, but that's it; I used it when I had that advertising virus/trojan enter my computer; made a thread about it in January I think it was).
