Hi ndxer, welcome to the forum

You are talking about Comodo BOClean, and NOT about Comodo System Cleaner

If your problem was caused by BOClean, I want to examine first what happened. Can you please :
- Open the BOClean menu by right clicking its traybar icon
- Left click "Examine report" ( DON'T clear the report log so click NO on the pop-up )
- Copy and paste its contents here
Thank you

Greetz, Red.
