BitDefender was rated #1 this or last year.
ASC was reviewed extensively on the source site:
For a good, in depth review head on over.
and I suggested the review be read. The OP isn't an ad nor is it meant to be. It was written for two purposes:
1. To aquaint people who might want security software with a free offer for excellent software (I take it you have it installed but don't think so?).
2. To remind people about the 7/9 deadline regarding net access for those who might have the DNS Switcher virus on their systems and who need to scan for it.
I really didn't expect this from you, and it hurts.
