Please, can someone help me? I use Window 10 and the Firefox browser. Yesterday, I did my usual morning Kaspersky Internet Security update after switching the laptop on, and a restart was requested. Since then, I have been unable to access ATG on Firefox. I have no difficulties accessing other websites on Firefox, including other forums, and I have had to resort to using Microsoft Edge to access this forum. The screen message I keep getting for ATG only is this.
