Best Antivirus Program For Win XP Home?

I seem to have a lot of trouble with getting trojans, viruses, etc. Most of the time my antivirus I use now (avast! home) will catch these things, but sometimes it won't.

I tend to download a LOT of content from torrents, like movies, tv shows, music and applications (to test to see if I want to buy them)

I suspect (more like assume) this is where they come from.

What do you all use for antivirus software and what in your opinion is the best one out there? I will buy it because I am getting sick of having to format my drive every few months because my virus program can detect the problems, but can't seem to fix them.

Thanks!
