I'm new to Ubuntu.
I'm now setting up an OwnCloud server which supports ClamAV file scan.
Since most of the users connected to the server uses Windows OS, can ClamAV scan for Windows virus?
I also did some research that such as BitDefender. It clams that it scans real time, if someone upload files to the server, will BitDefender scan the file even OwnCloud doesn't support?
By the way, I heard that if I update the system frequently, I don't have to install any antivirus that scan for Linux virus. Is that right?
