First of all, I suggest you upgrade the antivirus software, kill computer viruses, clean up the registry and garbage, and then clean up the C disk with the disk that comes with the system.

You can choose to clean up the following: (Please open the hidden file first, and then set it in the folder options. Some files to be cleaned may not be visible until they are opened! )

1, start-run, enter %temp% and press enter, and then completely delete the contents of the open folder. Note: This is a temporary document, and it will get bigger and bigger with the extension of application time. Regular cleaning is recommended!

2, open the Internet option, and then clean up IE temporary files!

3. Open c:\windows, and delete all folders that are hidden and displayed in blue!
