We have been working on PCs for 12 years now and have always trusted in Norton’s Antivirus.
I DO NOT like the Norton’s 360 or the Norton’s Internet Security, just the regular old antivirus. We have hundreds of PCs that are protected by Norton’s and I have to say that none of these systems ever get viruses. I have seen systems with every other antivirus protection come in from time to time. We make a lot of money off of folks that do not use antivirus or that let their subscriptions expire. So, use Norton’s Antivirus (just the Antivirus, not 360 or Internet Security) and make sure that you are getting your updates. Also, these guys have done a good review of what is out there: http://www.software-antivirus.com/program/kaspersky-antivirus-review.html
