Hi, jamesedward and welcome to Gameboomers! It's always good to see new members drop down in the Glitches forum!
I just put the free Malwarebytes on a laptop I was cleaning up for a friend. It simply asked me if I wanted a 15 day trial of the Pro version and I said no. When Mad's 5 days is up, the popups will simply go away.
In my PC corner for the winter, gaming, knitting and reading.
