Sorry for the delay getting back to you, I've been away.
My processes are stripped down. Probably half a dozen not needed on this machine. Also, I do use a program called Start Up cpl (by Mike Lin ) to stop apps from loading at start up.
I use Zone Alarm 4.5 as firewall and have no other Anti-Virus app installed.
Standard Shield was set to High, then custom with several file extensions added ( found this on a post , maybe one of Technical's) and finally just set to normal. It seems that everything I do on this machine is scanned first. I'm not sure if thats good or bad.
