i'm new,but wath's wrong with F-Secure Internet Security 2014!
each I click the "Exclude files from the scan..." or "Change application permissions..."The program crash.
The version mismatch is caused by Internet Security 2014 diagnostic tool not having "Windows 8.1 compatible" manifest in it. In this case, Windows lies to the program, giving it Windows 8 version numbers. It's harmless, really, but will be fixed in next release.
Regarding the crashes, please contact support.
