When I bought my computer I was using Norton AntiVirus, soon I switched to Kaspersky. I didn't like it too because it was slowing down the computer's performance. Then I installed Eset Nod32. It's a very good antivirus. Now, I use AVG. It is a free of charge antivirus and from the view of CNET editors (http://www.download.com) is also a popular one.
What antivirus do you use? What do you think of it?
