i've been using bitdefender for a little over a year, never had a issue till i upgraded the version i have is the 2011 internet security.
my issue is i cant seem to change websites without my p.c stalling an issue i have never ever faced in a year of owning it...its a very good alienware pc..ever since i got this new anti virus the performance has completely slowed down is there a reason for this? or would it be better to replace this software..
