My favorites:
1. Comodo - not bad, as long as you know how to config it,
2. Avast 2014 - many false positives, which it's annoying sometimes,
3. AVG 2014 - comes with a lot of bloatware, so be careful when installing it.
However, the best anti-virus, it's common sense! Don't open suspicious links, and do not open attachments and you will be safe.
