My windows fire wall wont start Ive tried starting it in services and the action center but no luck, i know their might be a hardware change or virus or malware that has done this but im unable to pin point it the date of any change because Ive only just realized that the firewall was off because i wanted to block a game from accessing the Internet. Ive scanned countless times but it says its clean. Also windows update wont install updates and system recovery doesn't work...Ive been trying to follow instructions that have been given to other people but with no luck, any help will be appreciated.
