How to completely kill 2345?

Before deleting, you need to put your computer into safe mode.

Safe mode is a special mode in Windows operating system, and friends who often use computers will certainly not feel strange. In safe mode, users can easily fix some errors in the system, which will get twice the result with half the effort. The working principle of safe mode is to start the computer without loading the third-party device driver, so that the computer can run in the system minimum mode, so that users can easily detect and repair computer system errors.

When we delete some files or empty the contents of the resource recycle bin under Windows, the system sometimes prompts the words "so-and-so files are in use and cannot be deleted", but these files are not in use. At this time, we can try to restart the computer and enter safe mode when starting. After entering safe mode, Windows will automatically release the control of these files, and then you can delete them.

If the computer can't start normally, you can use Safe Mode or other startup options to start the computer. Press F8 when the computer starts, select Safe Mode in the startup mode menu, and then restore the system as follows:

Click Start → All Programs → Accessories → System Tools → System Restore to open the System Restore Wizard, then select the option of "Restore my computer to an earlier time", click the Next button, click the date displayed in bold on the calendar to select the system restore point, and click the Next button to restore the system.
