Hello, I updated Windows 7 64 Pro recently - in November. After the update, my keyboard stopped working. And on the Avast icon in the tray there was a red cross, a notice - you are not protected. Avast protection screens were enabled, but there was no operating system protection.
Updated in October, everything was updated well. In November, after the update, I deleted the updated Avast - the keyboard worked. Installed a new Avast from the July installation file. I tried to update again, the same thing - you are not protected, the keyboard has stopped working. This time I returned to the system restore point, where the old version of Avast is.
