I don’t think many people understand this so i wanted to further explain. Turning the signatures off and just useing the comodo cloud will not have the same detection rate. Not useing the signatures will lower the detection rate i have personally did my own tests with this on malwaredomainlist.
Comodo cloud is not like panda cloud anti virus it’s so much different it’s more of a behavior blocker and a cloud. I would suggest you use the signatures and the cloud to have the max detection.
