I really hope you can help, not sure where to turn. For the last month or so my laptop has refused to open certain website, including bbc.co.uk, tripadvisor.co.uk, hmrc.co.uk, and it wont let me pay for anything online. Also I can't connect to iTunes. I'm not very technically savvy so no idea how to correct this. I've fun a full Kapersky scan and 'no threats detected'. I tried rebooting my laptop to a backup from just over a month ago and those websites will then work for a few days, before it goes back again. Can anyone help?! Thanks in advance.
