Hi. I'm using NOD32 v3, OA firewall and Winpatrol for on-access protection. I've noticed that after installing and running all these programs at the same time, my 'dummy' PC (an old Celeron M 1.4GHz w/ only 384MB RAM) slows down significantly. Could it be because of the overlapping HIPS of OA firewall and NOD32? BTW does NOD32 have HIPS?
