Well yes i tried to install avg.. but i read later that i must uninstall it and i did..
Then i updated mtj windows defender, then idk what happend but it just shut off again and when i press start again it simply says that its not in service.. i check services.msc but its gone from there.. later on i start having some black windows (command windows i guess) that disappear when i start my pc.
My wind 10 pro has expired like a week ago.. could this be the reason ?
