w32.spybot.worm Virus Keeps Coming Back!?!? Help!

I have been fighting to rid my PC of the dreaded w32.spybot.worm for
almost two months now. I had to re-format my PC - and boot sector -
as this virus was on my PC, but every once in a while (after
start-up), my Norton Antivirus tells me it found a w32.spybot.worm
file and it deletes it (usually the TFTP files). This keeps happening
after I visit websites that have pop-up ads (Since my re-format, I
have not downloaded ANYTHING from any website besides Norton and I am
not a Kazza user).

My firewall is enabled, I have all Windows security patches and Norton
running. What else should I do to prevent this spybot.worm from
re-infecting my PC? Should I use the Google Toolbar to prevent
pop-ups and see if that works?

Is it possible that the w32.spybot.worm is still on my PC (and that's
why it keeps re-appearing sometimes?)? How can I tell?

Any advice you can give would be much appreciated!

Thanks!
Paula

Has Spybot worm now become a file infector virus too? I came here thinking I knew the difference between
"self-contained" worm files and "virally infected" host programs and now find both to be false notions. Some
poster said that worms are viral and now someone says a worm infects files on a second drive - - what gives?
