CCleaner gets turned off by something

ccleaner is being turned off by something and then my restore points get deleted at the same time. I run all known spyware checks and virus scans they say all is good. And i do have some top line antivirus programs. i been fighing this now for a few months with no luck in finding why this is happening any help would be so helpfull :o) it has me stumped....

More info thanks Clifford.

Windows OS?

CC version?

AV program? (should not be more than one)

CC is being turned off how? do you mean a scheduled task, auto start, new monitoring feature?

Windows OS-vista home

V4.19.4867

SuperAntiSpyware

Microsoft Security Essentials

I get up in the morning and its not in my hidden Icons anymore i have to go to programs to start it back up. Sometimes it goes 5 days without being shut down by something.
