Yes, if scanner was effective would be good And you can hold "Shift" & click CCE scan...CCE will kill malware & unknown processes & start scan...hope I remember correctly.
In general Comodo is good, does have extreme protection, but it's full of bugs, some of which go back years. If they fixed this then they would be able to take on the AV industry, until then it won't happen. Also, a company cannot keep going without revenue, offering free software is good, but with out money you cannot keep developing the product, hence the long wait for product releases.
