Hello i have been using bitdefender 2011 since it was released, i ve done several formats etc switched some operating systems etc now ive been using it with windows 7 ultimate 64 for about 6 months. Recently i did a format some days ago and today suddenly the protection level is changing by itself from aggressive (my preferred option) to a custom level that excludes networks and seems lower than the permissive level bit defender offers. I did an update like always scanned and did a defragment. It keeps happening after hours it changes... i am little afraid of some expert hackers changing it or some kind of virus? any explanation for it?
