We have remedied the false alarm by the Windows Defender, by Microsoft, flagging the game as a malware. If Windows Defender is still detecting the game as a malware, kindly observe the following procedures to correct the situation. ※ Also, please be advised to back up all your save datas into a separate folder, in a different directory from the game. 1) Uninstall the game by Right-clicking on the game in the Steam client, and "Delete Local Content". 2) Re-install the game. Kindly note that verifying game cache will not work for this remedy action. 3) Notice 2 folders appear in your game directory (...\Steam\steamapps\common\), namely “River City Super Sports Challenge ~All Star Special~”and “River City Super Sports Challenge All Star Special”. 4) Locate the save data “SAVE00.BIN”, found in:...\Steam\steamapps\common\River City Super Sports Challenge ~All Star Special~\USRDIR\SAVEDATA\ and copy over to:...\Steam\steamapps\common\River City Super Sports Challenge All Star Special\USRDIR\SAVEDATA\ 5) Boot the game normally. ※ After verifying that the game is able to boot up normally in your system, and you have safely copied over your save data, you can then proceed to delete away the “River City Super Sports Challenge ~All Star Special~” folder. ※Apologies for the inconvenience caused.
