http://www.spazmatic.net/partners/ccleaner/ Every weekend I run my Ad Aware, Crap Cleaner and Backup my day job work files, Then shut down and restart. Every late evening my AVG Grissoft antivirus software is set on scheduler to run automatically. Michael B. P.S. Since doing this routine without thinking about it on all three of my computers, I have less Windows lock ups in 98 and XP home and XP pro run very fast and without problems. P.S.S. Amazingly all of this "maintainence routine" uses freeware and does not screw up my computers like Norton did.
