CCleaner disappear

CCleaner for Windows CCleaner Windows Bug Reporting
1

I cannot be sure if this is a bug, but, as it's the third time that it happens I can say it's a recurring failure.

I work on a Windows Dell 5810 workstation with Win 7 64B.

At startup I cannot find my CCleaner64 software installed. Totally sisappeared.

For the past I reinstalled and run. I have a scheduled daily run that works ok, when the program exists.

Few days passes between one "disappear" and the next.

I have Avast free as antivirus and MalwareBytes Premium as anti-malware.

I read of similar event from Windows 10, but I have windows 7 64 .. then ?

Please help, thanks

Does it just disappear from the desktop (the icon) ?

Or does it disappear from C\Program Files (x86) as well?

Is it still listed in Programs and Features when it disappears?
