I use AVG but it shows me advert popups every day which is extremely annoying. So I am looking to change...
from what I read in this thread there isn't a universally recommended solution
common sense is the most helpful but sometimes just not enough, sometimes you have to work with USB devices from other people, sometimes you're going to download files from what looks like a legit server but that has been hijacked, etc, at the end of the day you're always safer with a decent antivirus (IMO)
edit: I found this
http://www.tomsguide.com/us/best-antivirus,review-2588-5.html I am going to try Avira first since it's been ranked #1, and then the second one if I'm not satisfied, etc.
Avira can be installed via Ninite which is great
edit 2: goodbye AVG! you lost another user
