Maybe if I wasn't using a two way firewall, I wouldn't have a problem with BDFA. But that doesn't explain why I have to turn off the power button then turn it on again when it goes to sleep or shut the lid. No such problem with any other av I've tried on this machine. ZoneAlarm® Free Antivirus + Firewall 2013 is equal of BDFA without bugs! I should say BDFA would be the equal of ZoneAlarm® Free Antivirus + Firewall 2013 if it didn't have bugs and had a fw. My point is that it will be one of best av's when fix the bugs!!! It's buggy! It doesn't have to have a fw, there are some good free ones.
