System Volume Information folder is necessary for system restore to work and is not recommended to delete. You can ignore this folder. Just to make sure your computer is free from virus I would suggest you to run the Microsoft safety scanner. Also check if there are any virus on game console storage.
Note: The Microsoft Safety Scanner expires 10 days after being downloaded. To rerun a scan with the latest anti-malware definitions, download and run the Microsoft Safety Scanner again.
Disclaimer: Any data files that are infected may only be cleaned by deleting the file entirely, which means there is a potential for data loss.
Hope this helps. If you need further assistance with Windows, let us know and will be glad to help.
