Three days ago I ran into a problem I do not understand. The problem is: at the start of the system, at the bottom of the monitor (in the tray) the "Avast" icon is crossed out with a red cross. I pointed the cursor and saw that the system is not protected. When I try to start protection nothing happens! Nothing at all! I already rebooted the system several times, and manually tried to do at least something - zero! What to do? Really have to reinstall the antivirus? Tell me, can I run it again somehow?
