I have been using Fix-It 4.0 (Ontrack) for years and I am using Fix- It v5 (V-Com) now. They both rock!!! Everything is included. Easy Recovery, Defrag, Speed up, Reg fix, Reg clean, snapshot etc etc etc. The only downside: v5 is way slower when running reg fixer than v4.
SpySweeper! It does a thorough job and finds more spyware than Lavas Ad-Aware.
