High CPU Usage when virus definitions are out of date
« on: July 27, 2013, 10:58:14 PM »
Whenever avast notifies me that a virus definition update is available, the CPU usage spikes making the computer almost unusable.  I don't see visible nag messages after I close the initial pop-up message, but the only solution that I have come up with to resolve this is to update virus definitions/engine and reboot.  This has been happening for several versions (not sure which, but I have updated the program at least twice with the same symptoms).

I am currently running Win XP SP2, avast 8.0.1489 (set to notify of available definition/program updates), Comodo Free Firewall (I get the same results with ZoneAlarm Pro).  This is a business critical desktop and I will not install SP3.  I prefer not to have automatic updates.

Any help in configuring avast or Windows would be much appreciated.

You're not allowed to use avast! Free then.

Well that solves my problem.  I'll un-install this steaming piece of shit and install something that actual works because I'll be damned if I'll spend a penny on something this poorly written and supported.
