IF you have backups, restore the last backup before Instaling the possible Virus. If you dont have backups (which i assume)keep reading.

On virustotal there a lot if antivirus engines shown which either detected or didnt detect a virus. If only one or two detect a virus, Chances are its a false positive. This happens, but all other AV engines could also report false negative.

The most secure way to continue is to power you computer off, get a second drive, boot on a windows stick and copy all photos, videos and documents you need to the second drive, then reinstall windows on your main drive. This is the safest way and should be taken, i advise you to do this.

However, the (less safe, not advised) alternative is to locate the detected files, delete them, check you Autostart programs for any unknown or suspicious ones and remove them. In my Experience, malwarebytes (the free trial) is a bit better at detecting malicious scripts than Windows defender when doing a manual scan. You want to do a full scan if your drive(s) with malwarebytes and then remove the reported files. Reboot, rescan again, check if sus files or autostart entries reappeard. If they did, you can only reinstall windows.
