OK thank you so much.
First reason why I meant I have something is that my Chrome will not run any more (sad face) so I Googled and found that it can be some infection.
Then I try many antivirus software but nobody can install some “driver” into boot sector so I was sure there is something…
Thank you again, I need to do additional research why Chrome will not run (I try to uninstall it many times but it does not helped).
