I will teach you a method. When you open the disk, do not double-click it. Click the back button first, and then click Open, so that the virus will not run automatically. Then download the latest version of the anti-virus software, restart the computer, hold down F8, enter safe mode, and then completely kill the virus. I think we should be able to kill them all. If that doesn't work, go online and download a virus-killing tool. There will be no problem. I don’t think the grid plate is needed. There is nothing left in that grid. The price is too high, it's just a virus, nothing more, don't bother yourself.
