Hello All,
I have just installed the latest version of COMODO Sytem Cleaner and after running a registry clean and a disk clean I am asked to resatrt the computer. On restart I get the message " CRCNAT.EXE not found - skipping Autocheck" and then it continue loading.

I have looked for both CRC32.ini and CRCNAT.exe but they are not on the system.

Can anyone help Please ???

Many Thanks
