Since it is anti-virus, you can only use anti-virus software to kill the virus. My windows firewall is turned off. Generally, I use anti-virus software to fix vulnerabilities, so there has never been a problem like yours. And you said that the pop-up window was denied access, which may be due to insufficient access rights, and the right-click administrator has obtained ownership. If you try again, it may be a system problem. After all, most systems in China are pirated, which may be a virus problem.

I suggest you start your computer normally, clean it up with anti-virus software, and then quickly fix the vulnerability. When you start diagnostic mode, you will diagnose the system. A problematic (pirated) system will naturally go wrong.

If the machine can't start now because of advanced virus, I suggest you reinstall the system. In addition, before reinstalling the system, if you need to transfer data, you can take out the hard disk and put it in a hard disk box, which is equivalent to moving the hard disk. Connect it to another computer and transfer it. Just pay attention to antivirus.
