new windows open by themselves but useless stuff?

Hi

If you are being re-directed then your system needs to be looked at by a specialist malware removal expert.

There is software that you can use yourself ( Malwarebytes for one ) but even this does not remove all traces of malware.

A good malware specialist will walk you through cleaning your machine step by logical step.
You will not get this specialist advice here.
I can recommend http://www.freepchelp.co.uk
There are good guys there.
There are, of course, other sites that can help you.
