It can still be the virus scanner because I/O takes a lot of time in which the computer can do nothing. You don't see that registered as processor time for some reason (I don't know that much about computers). So try to switch it off for a while and see if that makes a difference. I hate virus scanners with a passion and I always try to switch them off at work. At home I don't have them. Never had a virus in 20 years or so.
