Blocked without warning

When I installed KMPlayer x64 on Win 7 Pro, F-Secure Antivirus prevented the program from running but provided no warning about the block.

    Sorry for my reply. I am only an F-Secure user (their home solutions).


    One option is to transfer KMPlayer executable to F-Secure Labs:

    with description about situation.

    As my own feedback -> I tried to install KMPlayer x64 on Windows 7 and then to launch it (with installed F-Secure SAFE under system).

    It was not possible indeed. But with disabled F-Secure SAFE or with turned off DeepGuard module - KMPlayer x64 is launched.


    I am not sure does it block by F-Secure DeepGuard or its own 'protection' by KMPlayer functionality (as prevention against hooks or deeper analysis by third-party applications). Or even if KMPlayer does not expect any delays with opening and if there is certain time delay - it just not launched at all. When we run applications - F-Secure SAFE do scan/analysis on-the-fly (so, can be 'kind of delay').


    // as temporary workaround - possible to exclude KMPlayer executable (

    But it will reduce security state (in general).
