Question

I have a game on steam called "skillshot city" which me and my brother have played for 100 of hours and now is getting marked for "suspicious"

Answer 1

First, secure the Steam account, email, and PC by changing the passwords and enabling 2FA/Steam Guard. Then contact Steam Support; they can explain what was flagged and help with the solution

Answer 2

If Microsoft Defender is marking a legitimate Steam game as suspicious, the supported options are:

1. Check whether the detection is actually a potentially unwanted app setting rather than malware:
   • Open Windows Security.
   • Go to App & browser control.
   • Open Reputation-based protection settings.
   • Review whether potentially unwanted app blocking is turned on.
2. If Defender is identifying the game files as malware but the files are believed to be legitimate, treat it as a possible false positive and submit the file to Microsoft for malware analysis.
3. If the game or related tools stop working because of a Defender alert, Microsoft documents a temporary workaround by adding an exclusion:
   • Open Start > Settings > Privacy & security > Windows Security.
   • Select Virus & threat protection.
   • Under Virus & threat protection settings, select Manage settings.
   • Scroll to Exclusions and select Add or remove exclusions.
   • Select Add an exclusion, then choose the affected file or folder.

Warning: adding an exclusion can make the computer or network more vulnerable to attack. Microsoft states this workaround should be used at discretion and at the user’s own risk.
