Windows 7: window 7 firewall error code 0x80070424

my computer is window7 ultimate 32 bit. Recently, I just got error code of firewall. I could not change firewall at all. the code error is like this.

error code 0x80070424 when I try to change it in Window Normal Start.
error code 0x6D9 when I try to change it in Safe Mode.



here are the pictures.

The error from the MMC means that there's no RPC endpoint available for it to talk to, and the error from the security center is "ERROR_SERVICE_DOES_NOT_EXIST". So, do you know when this first started happening? Is anything else happening on the system or in the event logs that might indicate a larger problem?

thanks for your response. This happened when I try to install one software which I downloaded from internet without scan. that time there are viruses effected to computer but I have Essential to clean them. since that time I never uninstall antivirus until now. this is my first problem of using window7 ultimate 32 bit and there is only one too. my computer starting window well but I need FireWall working back to making safe.

Please help me to solve it step by step because my knowledge of computer science is little.

Best to you.

Thanks

You might need to do a "repair" installation to repair the damage done by the viruses, although it's hard to say without knowing exactly what happened.

Repair Install

Hi, cambodany. Welcome to Seven Forums.

I suspect that the source of the problem is that your computer is still infected. Please go here to run an on-line scan from ESET.

• Note: It is easiest if you use Internet explorer for this scan. (If you use an alternate browser, it will be necessary to download the ESET Smart Installer)
• Turn off the real time scanner of any existing antivirus program while performing the online scan
• Tick the box next to YES, I accept the Terms of Use.
• Click Start
• When asked, allow the ActiveX control to install
• Click Start
• Make sure that the option Remove found threats and the Scan Archives options are ticked.
• Click on Advanced Settings, ensure the options Scan for potentially unwanted applications, Scan for potentially unsafe applications, and Enable Anti-Stealth Technology are ticked.
• Click Scan
• Wait for the scan to finish
• Use notepad to open the logfile located at C:\Program Files\Eset\Eset Online Scanner\log.txt
