I can't put some files in the exclusion list

After a full scan, Comodo has given me this 58 registry keys as you can see in this image:


Edit by Dennis2: removed the uploaded to well known image hosting site message

I read around the web that these are false positives.

So I tried all the options to put the keys in the list but every action is denied and Comodo gives me a message like this:

Add to Safe Files:


Send to COMODO as False Positives


Traslations: “<> is not possibile for some files”

Add to exclusions


Traslation:“Add to exclusions is not possibile for some files. Do you want to disinfect?”
Even if I disinfect, the next scan continue to show me this file as “dangerous”

Sorry for my english but I’ve the italian version of the suite and I don’t remember the right traslation.
