Sabotage or Feature?

 
When I started my iMac this morning Clean My Mac Helper did not start. Checking, I found that this and Clean My Mac X were completely removed from my hard drive! Some of the folders were left, but they were empty. An old copy of Clean My Mac 3 was also gone, with just an empty folder. Even my bookmark for the complay link was gone from Chrome!

I found the e-mail confirming my latest renewal in my e-mail client and started downloading X again. We'll see...

Update: Got Clean My Mac reinstalled and ran it with no problems. Then I noticed that the main volume slider on my iMac was all the way to zero. No idea if that's part of the same problem. At least that was easier to correct.
