Update your antivirus

ROBLOX recommends making sure your antivirus is updated so that it isn’t incorrectly tagging ROBLOX. If you use the built-in Windows antivirus, you can update it by updating Windows. However, it’s easy to do if you need to check whether you’re up to date.

  2. Click “Check for updates” under “Virus & threat protection updates.”Check for update in Virus and threat protection

  4. Follow the steps to update your protection, if needed.Check for update in protection updates

If you use a third-party antivirus, you should be able to search for updates from the program’s main screen. For a program without that option, try searching in the Settings area.

Add an exception

Adding an exception to Windows antivirus and threat protection means that it won’t be flagged as malicious.

  1. Go to “Virus and threat protection” again. 
  2. Click “Manage settings.”Manage Settings Window
  3. Click “Add or remove exclusions.”Exclusions windows security
  4. Click “Add an exclusion.”Add an Exclusion
  5. Choose “Folder” and navigate to your ROBLOX folder.Select roblox folder
  6. Click “Yes” on the pop-up to confirm.

Keep in mind that Windows won’t scan your ROBLOX folder for viruses in the future. If you want to do this on a third-party virus software, the process should be about the same, except that you’ll have to do it from your software dashboard. 

Computer Maintenance
