Yes, I tried both of those but they end up with an .exe trying to run. meantime I rebooted and pressed Function keys at random and got into fix mode that allowed me to Restore to a pre infection time. Running Avast Anti-virus deep scan now and so far found 2 infections. Soemhow I got something called Win 7 Ant-Virus installed that would not me do anything without paying. Restore seems to have got rid of it
I think you need to start your PC in safe mode by pressing the F8 key repeatedly at start-up. Select Safe Mode with networking. Once into Windows download Malwarebytes, Run the programme and update it then do a full scan. Delete any problems it finds and restart Windows.
