I was already equipped with Bitdefender Total Security 2010 and the time of renewal approaching. I tested other antivirus to see if I was better but in the end I was constantly "pestered" by messages asking me to allow certain programs to access the net. Finally I returned to my first love Bitdefender and there miracle everything goes very well, no posts that still bother me more than if I actually had a real virus alert. And do not hesitate to take the ATTACHMENT version that is half price.
