I am using ZA Extreme Security with XP SP3 and Firefox 5.0
Since my last upgrade I have encountered problems with excessive cpu usage and I'm pretty sure ZA is the culprit. Often I find ZA is conducting a scan on startup and while that is going on everything else freezes. Task Manager tells me cpu usage is 100% so nothing else will run and I have to reboot.
I have used ZA for years but not had this problem before. Is there something I should know that hasn't been advised?
