Rich - while you wont often have as many system hacks with a MAC, it sounds like you do need a good hard drive house cleaning - dump the cache, history and cookies. Somewhere you have a trojan horse and/or some spyware that's allowing the MS garbage. There are a lot of pretty good freebies - I use AVAST and Advanced System Care - but not all are compatible with MAC. Go to CNET or PC World and see what they recommend for that system. I've had a minor glitch or several since Xmas when a couple of my GC messed my PC up - (and they did their mother's new business Blackberry as well)
