Can all PREFETCH files be deleted?

by multiplexusa / December 18, 2010 1:14 AM PST

I have CSRSS.EXE-12B63473.pf (33k) in my Windows\Prefetch directory. I read this is probably spyware or virus, plus all other versions in my system are only 6k. However, I noticed a .pf completely renamed/modified copy of virtually every Windows Service that actively runs existing in this folder, all of them with large file sizes. Finally, I read where some spyware like m.exe clones processes and "rides" WITHIN an otherwise legitimate Windows Service.

Therefore I have strong desire to axe everything in this folder. Can I? Thanks.

No benefit it seems.

But you see this done all that time. Go ahead.

Unless you shut down the prefetch/superfetch service.... windows will continue to load that area.

Perhaps some folks find a benefit to this service.

I've tried it both ways...on/off....nothing jumps at me.

I just run with it off and consider it one less area to give me grief.
