Antivirus Software
The well-known antivirus products tend to score close to each other in independent lab tests, so the differences you feel day to day are usually somewhere else: how heavy the software is on your computer, how often it pushes you to upgrade, and how comfortable you are with the company behind it and what it does with your data.
So instead of one ranking, this section starts from your situation. Pick the one below that sounds like you, or go straight to the provider reviews.
