Don't COMBO have a special quarantine area where it places files ? It just deletes them ?
It might be that COMBO have renamed them. It does not have an UI where you see files it quarantine ? and from there you can bring them back ? Most AV software has that.
( From AI :
The COMODO quarantine area is a secure, isolated section within Comodo antivirus software where potentially malicious or suspicious files are stored.
These files are encrypted and prevented from running to ensure they cannot infect your system or cause any harm)
So you might need to restore them from within COMBO.. you will not find them your self
Maybe change AV software. Often built in Defender is good enough unless you don't have special requirements.
Problem with all FileManager is that AV software finds them suspicious.. Here is an app that have code much code in it to handle files, copy, rename, and delete them.. That is very suspicious. So all FileManager often lots gets false positives results on them. And there is nothing to do about it.
