Hi Libyan expert :)

This folder is used to store certificate pair keys for the system and its users. I wouldn't touch the files there as you could delete certificates used by Internet Explorer or other services, which would make them unusable after.

What Antivirus program are you using?

It's a known issue with ESET products. See the following thread:

https://superuser.com/questions/538257/why-are-there-so-many-files-in-c-programdata-microsoft-crypto-rsa-machinekeys

Disable SSL Scanning in ESET, and it should stop creating a lot of files in there.
