...yes. That's about it. No idea why the question mark though.
A false positive, in virus scanning, is when a service thinks something is a virus when it is not.
Not all services are perfect, and some may think that just because a program does a particular set of things or are programmed in a particular way, then it must be a virus.
This is why those same services sometimes allow you to submit a false positive report, so they can look into the wrongly accused program by themselves and manually change its status.
