Comodo Cloud AV Review By Malware Blocker

Not really sure what is going on with this test. If there is no internet connection, of course CCAV won't detect anything. This reviewer said he redid the scan with the internet connection on. Any functional AV would be able to detect at least some of the threats in a malware pack as they are usually from a malware depository which has a lot of older samples (despite what these YT testers say). I think the connection still wasn't working properly, or CCAV didn't register the connection properly.
It could also be an issue with the VM/not restarting the computer after the installation. It looks like he skipped the initial quick scan, so it is possible that he didn't restart after installing CCAV. For most security programs a restart is needed to properly complete the installation and for the services to register fully. Also sometimes programs can behave abnormally when running in a VM.
Another thing that is confusing me is why this guy is saying that CCAV is compatible with other AV's. Just because it uses the cloud doesn't make it compatible with other AV's. The only real difference is that the scanner is using the definitions in the cloud rather than locally; the scanner still needs to access a file to scan it. Also, based on how Melih is questioning the need for another AV, I assume that CCAV wasn't designed to work along other AV's. I'm sure that some AV's can work along with CCAV naturally, but it is dangerous to assume that CCAV is compatible with most others. Nowhere does it say that CCAV was designed to work with other AV's.
