Computer help - Cookies

Okay I'm terrifed. I thought McAfee protects me. In the log, it said realtime virus checking was disabled, yet McAfee says all my security programs say they are fine. I used Spybot to scan and I have a Trojan among 1900 or so other things........I have to register with Spybot to have them removed. Should I do that ?

I'm on our other computer right now, the cookies seem to be fine here, although the computers are networked.
