can anyone out there help. I am not great on computers and spent all yesterday trying to sort out this problem. I can get on the internet and yet when i try to go to a site the whole screen is blocked and comes up with 'about blank' On the white screen is a warning telling me I might be at risk and then I have three optins to get out of it by buying norton antivirus 360. It is an american site and I can't beleive norton would do this. Is it a scam and how can I get rid of it. I just can't access sites unless I use the blank screen to purchase this ameican Norton. Thanks fir yoiur help!
