The Antivirus Cloud is equipped with an automatic update feature, so set it and forget it!

It is generally highly recommended to first uninstall your old antivirus solution before installing your new one. This is because two antivirus programs running on the same system can work against eachother and can significantly slow down the system.

As long as the device you are running the Antivirus Cloud on has an internet connection the Antivirus Cloud will work.
