Dear users, hello!

If you have more than one antivirus installed on your computer, please keep only one test, as antivirus software may have product conflicts. You can also check with the following suggestions.

1.Check whether the CPU usage is too high, if so, try to stop the process that is too high. If your computer is infected with a virus, it will also cause some processes to be overly occupied, so we recommend that you try to upgrade the virus database to the latest version and test the virus to rule out the virus problem.

2.Try tweaking the virtual memory, or upgrading to fit your computer's memory.

3.It can be cleaned up by junk file cleaning tools carried by third-party software, or it can be cleaned up by Windows built-in features, such as the "Disk Cleanup" function and the "Disk Defragmentation" function.

4.You can uninstall the software that is not commonly used on the system by adding a removal program.

5.Enter the msconfig command during operation to optimize the boot items and improve the system boot speed.

6.If your operating system has not been reinstalled for a long time, it is recommended that you also use the above methods to back up important data and reinstall the system for testing.
