You should use Avast instead. It's completely free, but still very good.
As a tech I agree whole-heartedly with this.
Avast!, even the free version, is currently the best, and its boot time scan gets out crap those other two can't even touch.
You might want to get a free firewall along with it, but its really great & keeping your (crappy, insecure) Windows box safe.
...or you could just delete the Windows virus infecting your machine, install Linux, and stop worry about that crap.
