Judi, quoting from you:

"It might be a browser hijacker because tonight I got redirected to sales sites when I tried to search something."

"They were not happy and send me pop ups saying I need genuine Windows and I don't get any updates besides security."

Both of these sound like PUPs to me. Microsoft will never send an owner of a genuine version of Windows anything like the latter.

I suggest that, in order, you:

(1) Download the latest version of Malwarebytes but don't install it.

(2) Go off-line.

(3) Delete your current version of Malwarebytes.

(4) Install the new version of Malwarebytes and run it.

(5) Go back on-line.

With luck this should sort things for you .
