When I'm using Google chrome, I cannot go to site with "http://". And following someone else's advice, I checked the public keys for Google and Facebook in the certificate information and they both shared the same public key beginning with 30 81 89.
It started when I plugged in my external hard drive.
Also, I do not know if it is connected but windows firewall gives the error "Windows Firewall cannot change some of your settings. Error code 0x80070424" when I try to start it while windows defender gives the error "the specified device does not exist as an installed service. (Error Code: 0x80070424)"
I also attempted to install Microsoft security essentials but it gave me the error message "error: 0x800b0001"
I attempted to do a system restore but that failed too.
Right now I have no idea what to do other than just format the whole thing. An y advice on what I should do?
