Hello there, drugo.

Yes, you can delete the contents from the Prefetch folder but it won't make your PC to "go faster".


What is the prefetch folder?

More than enough explanation

There never was a reason to purge Prefetch. You should leave it alone.

No it won't...Prefetch files are an index not the actual executable files themselves. There is no reason to clear it. Prefetch and SuperFetch do not store copies any where. If the files a virus uses are gone, they are gone.

The simple answer is yes, you can purge prefetch without issues.
There is no real reason other than clearing out old data, no other reason.
If you have a cleanup tool that does it, there i no reason to tell it not to clean it.
