You should scan your computer with Malwarebytes AntiMalware to make sure there isn't something doing that to your system.
Malwarebytes.org

Then try this tutorial to find and fix any corrupt files you might have,

i think i know the reason why the same problem happens again when i shutdown the computer, because before i shutdown the computer, i always run the "CCleaner" to clean the registry...i think thats the reason why this problem happen again and i also scanned it with malwarebytes and found i think 4 infections.
anyway sir thank you for the hand and i really deeply appreciate it.
and also sorry for my bad english
