Still getting this prob. Although the message insists on popping up (only with ThinkBroadband) it doesn't prevent the website loading.
Though not consistent I haven't identified a pattern yet.
Kaspersky suggest unchecking 'Scan encrypted connections' and 'Do not use proxy server'. Neither has made any difference. Going through their Protection Settings identifies 'Web anti-virus' as clearing the irritation when unchecked.
Oddly, seems to occur on IE11 but not now GoogleChrome, but I need further checks on this.
Kaspersky now request submitting their ReportMaker.
Very puzzling. Any thoughts?
