Suddenly and without warning just today, I get a security warning when trying to log in to my @Tiscali account using my usual shortcut. My Avast anti-virus software immediately flags up a security problem and Firefox refuses to go to that page. I can log on to my Talktalk account, but when I try to get to my emails through that route the same security warning appears. It is only happening on my Windows desktop; I can still access my emails on my Ipad and my Android phone. Does anyone have any advice as to what I do about this, please?
