i have an ASUS laptop , and since a month ago my video camera led (the camera is integrated in the laptop) started to light up wich means the camera is on , 5 minutes after that 3 html url opened up in opera browser and all of them were porn , i had avast antivirus on it plus windows defender activated and avast doesn't work at all now , and if i try to install another one or the same one i can't because it's says that i don't have permission to install , but i am logged in as the administrator , i run the file as administrator , i tried to run it with cmd , i disabled smartscreen and it still doesn't let me , plus i can't open any file in C:\Program Files because of the same reason that i don't have permission , and for some reason i have like 8 antiviruses folders in program files that i never installed like AVG , Avira , Nortorn , Baidu . I'm totally lost , if some of you have any idea what could've happened or how can i fix it please help , i will try to reinstall the windows to see if it helps , or use the tor browser after the install (if this really is a hacker).
