ive never had an issue with free version, and its only the extras that run out after a month. 2012 version has firewall as well they stopped including it in this years version. so hunt for a 2012 download online. other than that its buying one, kaspersky is one of the best, like 60$ but u get 3 keys with that $ so not bad if you're like me with 4 pcs in the house
