My computer had been sending up various ads whenever i went online so i went to PC world and downloaded a adware and registry cleaner. Indeed they helped and my system ran a lot faster but one every now and then the registry cleaner would keep track of any unknow entries. I just deleated them and now i cannot login to windows anymore. Evertime i type my password and press enter it starts loading but then immediately logs off. I remember being unable to open any applications or programs that day that it first did that and when i restarted my laptop it just wouldn’t load. Does anyone have any suggestions on how i can repair this or do i need to reboot?
