I just recently upgraded my ZoneAlarm Security Suite (ZASS) to version 7 - the clean install went OK - but afterwards my cpu usage went up to 100% every few seconds - I narrowed the problem down to TrojanHunter Guard. I sent a message to Mischel Internet Security about the problem. Other Security programs I am running : Benign(b9); MailWasherPro; Nod32; Prevx1; Sandboxie; Spyware Doctor; CounterSpy; SUPERAntiSpyware; WindowZones.
