Error Code 0x80070424 with Windows Firewall, Defender in Windows 7
Tried to allow access for a program in Windows Firewall, it said i needed to change settings to default, so I clicked it, then an error code popped up reading "Windows Firewall can't change some of your settings. Error code 0x80070424". The same error
code pops up when I try doing anything in Windows Defender.
I cannot find Windows Firewall or Windows Defender in my services list. From researching this problem, I have concluded that I possibly have/had malware or a virus or something that deleted these and possibly other things. I would like help. Thanks

I’ve seen this issue on several different fronts, and the majority of those were virus related. The Key to resolving this is to first run a virus scanner to remove the infection. Some viruses such as rootkit viruses are a little more difficult to remove
but it can be done. The viruses can leave residuals that can still cause issues, things like the inability to turn on or configure the firewall or other security applications. Once the virus is gone, work to resolve the other issues that they caused.
First thing, Scan for viruses and other malware. If you don’t currently have a virus application, try Microsoft Security Essentials here. There is also a new tool, Windows Defender Offline Beta , you download the tool, burn a CD and then boot from that CD,
this tool scans for malware that loads as soon as you start your computer. See
What is Windows Defender Offline Beta? to get the download.
