Surely the av should have picked this up straight away?
Unfortanatly this cannot always be done, it can pick up the bigger ones normaly, but viruses/worms are programed to avoid detection, but they can always be found if you do a scan, thats why most av companies advise you to do a scan at least once a week.
Also if you put the resident scanner to high, it should pick up more while in memory.
Also I have found that I have a toolbar on my pc http://searchweb2.com/passthrough/popupbaropener.html.
This is spyware/adware, not a virus, have you tryed the new version of ad-ware on it, or the old version new version of ad-ware (the new version came out 2 days ago on the 9th).
Also you could try other spyware scanners such as
spybot or
spysweeper .
If these problems persist, post a hijackthis log here, there are people who can advise you from them.
