I have to say a great big thanks to everyone who's helped me on this forum
I didn't get any advise at all from the security system I paid 83 Euros for last November, they just kept asking for another 100 euros to remotely access my system and see if I had a virus.
I have yet another question....sorry ... I was told ages ago not to have 2 security systems at the same time as they would fight against each other, I've no idea if this is true, or if there are some that you can safely have at the same time. I downloaded Malwarebytes Anti Malware on free trial and it identified an Adware virus and got rid of it, I'm now thinking that I'll buy it, and replace the system I have, other than keep them both, can anyone say if this is my best option please? Thanks again for eveyone's help, I relly appreciate it.
