I was playing a bit in my virtual machine , to see how Comodo did.
And it did well , but after that i scanned with Malwarebytes , and it said it found all kinds of Malware in the quarantine folder of Comodo.
See screenshot below ,
Whats the dealio ?
not a big deal those all malwares are in good place 
but if you think those are threat to your system then simply delete them from comodo’s antivirus UI :-TU
true , but why does allot of malwarescanners find it , Malwarebytes also finds malware in quarantine of CCE.
quarantine leak ?
umm not think so i also scanned once my systen with MB and it found some threats in quarantine . so i think its normal nothing to worry .
Add the Comodo quarantine folder to the Exclusions of MBAM. There is no need for the quarantine folder to be scanned.
