That's a totally false report. I used this fix last year and I can guarantee you that it isn't malware at all. This fix also hasn't been updated since October the 18th, 2021 so it couldn't of been modified since the last time I used it either. Don't always believe these virus reports as 90% of the time they are completely false especially with files like these that patch other exe files.
I assume this fix does not work while using GFWL as the game will just show a black screen and then just crash to desktop when I try to use this fix with GFWL enabled. I also know this is off topic but do you happen to know if a 21:9 fix is available for Kane & Lynch 2 as well?. I ask because I can't seem to find any fixes online and the game doesn't seem to support 21:9 natively as the screen just seems to stretch at that resolution.
