Will the security software that I am using on XP suffice for Windows 7?

"No, those are all fine, although you'll probably need newer, windows 7 compatible versions of some, due to the increased security features (Relative to XP, anyway, it's a step down from vista!)

You can get these off their respective websites, so everything's shiny, cap'n, not to fret."

"My only suggestion - find out if each is compatible with Windows 7. The kernel is different, the security is different.

CCleaner and Defraggler definitely work, but the newer versions preferably."
