Trojan.Vundo?

I ran the Symantec virus scanner as suggested in the FAQ and got the following:

C:\WINDOWS\SYSTEM32\yabaa.dll is infected with Trojan.Vundo
C:\WINDOWS\ServicePackFiles\i386\tcpacc.dll is infected with Trojan.Vundo
C:\WINDOWS\Downloaded Program Files\bridge.inf is infected with Adware.WinFavorites
C:\Documents and Settings\Kate\Application Data\Sun\Java\Deployment\cache\javapi\v1.0\jar\arc.zip-53b42299-18bf6259.zip is infected with Adware.Winpup

I downloaded FixVundo from Symantec, ran it, and it said that Trojan.Vundo was not found on my computer. Being a rather technologically inept person, I'm confused. Did I do something wrong, and if so, what? Suggestions?

Thanks. :)
