I am compiling a list of the most used and overall most needed PC utilities. I'm going to use the list for a project in one of my computer classes. They can be free or purchased. Thanks for any help.
XPY - does common registry fixes for you
Test Disk - it saved my ass, repairs/rewrites boot sectors and file systems on hard drives to allow for data recovery
Zonealarm Firewall - free firewall
Spybot: Search and Destroy - spyware remover, catches stuff adaware doesn't, just as adaware catches stuff sybot doesn't
