So I had a virus (seems like many people have gotten it) that kept giving me pop-ups stating that I was being infected and needed to download certain anti-virus programs etc. I thought I removed it using RKILL, Malwarebytes anti-malware, SUPERantispyware and then ATF-Cleaner. However now I have a symbol at the bottom right hand of my screen. It's the Windows Shield and its red with a white X on it. When I click it, I am shown a page saying that my windows firewall is off, and both my automatic updates and virus protection are on. However when I try to follow the different steps to turn on the firewall (like going to start, control panel then double clicking windows firewall) I cannot activate my firewall. The bubble that you would click to turn on the firewall is gray and can't be clicked. I also tried to restore the firewall to the original settings but that didn't help either. Any thoughts?? I'm at a complete loss here and my scans are clean.
