Alan - the overall thing is:
If you use the internet you have to take some responsibility for your actions
Football streaming sites present you with tons of advertising, and a stray cursor can 'click' on stuff you don't intend
Porn sites are notorious for association with viruses and malwares
So if you're going to view these sites, and if there's any vulnerability at all on your computer, you'll get similar problems again.
You can't be wrapped in cotton wool. Lots of folk on here advised you in your earlier post on how to do a system restore which is kind of what you paid someone £30 to do. So you either choose the paid help, do the DIY or stay safe online.
