file is changed crossfire.exe

hey !
well i have a big probmlem .. everytime i try to open [CF] i get the message i''ve attached to u .. although i''m sure that there isn''t any thing happened to the files of the folder cuz i use shadow defender and that''s what shadow defender does : "Shadow Defender can run your system in a virtual environment called ''Shadow Mode''. ''Shadow Mode'' redirects each system change to a virtual environment with no change to your real environment. If you experience malicious activities and/or unwanted changes, perform a reboot to restore your system back to its original state, as if nothing happened."
i hope u help me quickly
