How do I remove this virus from my PC?

Yes,
Download this application Malwarebytes Anti-malware ethier using your computer (if able) and other computer and transfer the dowloaded exe to a usb stick then take stick to the other machine
disconnect infected computer from internet (remove network cable from the rear of the machine,install, run a full scan, don’t worry about the update yet, once done, show results, select remove selected items and reboot when requested.

the above should help remove this infection, after the reboot update Anti-malware and scan again and replace or update your Anti-Virus. If you have Norton remove it unless it still under subscription. Some good Products are AVG free and internet security (paid version) and kaspersky internet security (paid but fair cheaper than Norton)
