If your web browser is constantly being redirected to sites that display a Windows Firewall Security Damaged notification, asking you to call a support number to fix it, then it is possible that you have adware program installed on your computer.
The bogus “Windows Firewall Security Damaged” alert is shown in such a way as to trick the user into thinking their computer has crashed or that a virus has been detected on the computer. It does this to try and scare the infected user into calling one of the listed numbers in order to receive support. In reality, though, they will only be greeted with people who are trying to sell them unneeded support contracts and services.
The “Windows Firewall Security Damaged” pop-up will have this message:

The scammer will typically attempt to get the victim to allow remote access to their computer. After remote access is gained, the scammer relies on confidence tricks typically involving utilities built into Windows and other software in order to gain the victim’s trust to pay for the supposed “support” services, when the scammer actually steals the victim’s credit card account information.
