it means its on
It would enable your antivirus to detect viruses the moment it enters without scanning.
enable = turning a thing on

disable = turning a thing off

since you did not include the context of the thing that it's saying to enable there is no way anyone can tell you whether or not this thing is safe... however, if it's an option within your virus scanners settings then most likely it is a good thing.

If it is the anti-virus itself that is enabled or disabled you absolutely want it on (or enabled)!
