Constant Disk access

Can anyone tell me why explorer.exe constantly access the comodo executable (cpf.exe) multiple times a second. Using the sysinternals tool “filemon” I can see the access which is an OPEN, QUERY_INFORMATION and a CLOSE command, constantly. Causing Hard disk to be in constant use.

Also, comodo is constantly accessing my Skype executable every few seconds ? reading the skype directory structure and then accessing the .exe.

All very odd, and I need to turn it off - Any help appreciated
