Annoying pop-ups and something called 'Friendschecker' has started appearing on my webpages. it highlights random words in red and underlines them and pops up a box with a link to divert me to another page. And my net is running really slow.
I checked net advice but it is a bit conflicting and none of things I tried worked so if anyone knows how to block it that would be appreciated.
I'll not be able to get back to my PC for a couple of days but TIA.
