Can anyone help? I have this problem called malware. So when I click on a google link, it takes me to an advertisement site.

I’ve been able to get my hands on malwarebytes but when I try to run it, nothing happens. Someone told me that
the software that I’m dealing with may be smart enough to block the programs that can get rid of it from running.
Please if you’ve had this problem and were able to fix it I’d appreciate any feedback.
