Has anyone come across this before. My wife loves playing spider solitaire, if my MacAfee security suite starts downloading whilst she's playing everything starts running slow and my mouse becomes very hard to control. The only way I can get things back to normal is to reboot. This is when I find out it's MacAfee that’s the problem as it immediately starts to download updates. I’m on broadband use firefox as my browser, running XP home with a 2.5ghz processor and 512Mb ram. any help would be gratefully received, as she’s doing my head in.
