Can I delete these files?

[jbirmin693]

Hi, my McAfee has been going crazy with files that end with .pf. I found them in c:windows/prefetch. I would like to know if I can delete them all without causing any damage to my computer or other files. :-/

If Mcafee is going crazy then you probably have a parasite.
Ccleaner will remove the ones that haven't been accessed for a couple of weeks but there has to be a reason for Mcafee complaining.

You can actually dump the entire contents of the prefetch folder (not the folder itself) and window will rebuild it. The only downside is slower boot time until it is rebuilt. After you do this, boot to safe mode and rerun your AV. You might also want to run AdAware and Spybot. I do agree, there's a reason McAfee is complaining.
