F-Secure Blocks Games

Hello @Yuuta 

Thank you for reporting us the issue, sometime the F-Secure program will try to block or consider certain programs or applications as a potential risk. This also might be highly considered as a false-positive file. To attend to this issue, we have a Sample Analysis Department (SAS) to help verify these files. Kindly send these samples for verification to our SAS team. They will then liaise the issue with you directly. Please go to the link below.
