Re: Antivirus Question
Oh, watch out with this kind of posts, it's an spiky topic :P
As you said, once your license had expired your software will keep running but you wont have updates until you renew it.
By the way, about the free antivirus, I use to visit the av-comparatives website because it has a ton of interesting reports about viruses and malware security and some free antivirus make some commercial solutions bite the dust pretty badly, specially Avira.
When choosing an antivirus you should pay attention to a few parameters such like the resident protection (common viruses registered in the company's data base) and the heuristic protection (viruses not discovered yet or viruses that can mute to be undetectable).
