i have recently recovered from a virus attack on my pc, and i now have some missing files that were most likely deleted during cleanup.

i don't want to lose all the software and data that i have accrued since i got the computer.

My friends said that cleanup by steven gould is a good one. What do you guys think? I could really use your help, my computer is running slow & i have ran my spyhunter & ca anti virus & a disk clean up.
ccleaner is old be better than that!
