detect currently installed anti-virus [duplicate]

Answer 1

Yes there is. You can use WMI, I assume you are asking about Windows, to check installed instances of an anti-virus program. It is quite simple from C# and this link gives a good explanation of how to do it. It is also possible to access WMI from C++ and that is explained here. Also for anything WMI related I highly recommend the WMI Studio.

Answer 2

It depends on the AV software and the OS but it looks like you can use WMI. Here's an example on using WMI script - using WMI from C++ is outside of my knowledge, sorry.
