Windows 7: Unable to enable windows firewall , error code 0x8007042c

Unable to enable windows firewall , error code 0x8007042c

I'm pretty sure it was caused by some virus that disabled it. Windows firewall authorisation driver stated that >> This device is not present, is not working properly, or does not have all its drivers installed. (Code 24)

I had uninstalled my trend micro titanium from my laptop and installed microsoft security essentials ... And security essentials keep on detecting potential threats. I cleaned it and restarted my laptop and a blue screen came out said that some errors preventing windows from opening and the whole system restored back to few hours before ... But still, firewall was unable to start windows firewall ...

Solutions ?

Well the situation now is :

I tried to use microsoft safety scanner or microsoft security essentials to do a scan for my laptop and remove the virus ...

After removing the viruses found, it needed a restart to completely remove the virus, but everytime after restart, windows is unable to open and leaded me to windows error recovery and ask me to do a start up repair. Even with start up repair, windows cant fix the problem and ask me to shut down ...

My only solution was to do a system restore to few hours back ... Now my trend micro is still here and not yet been uninstall, worse still, now my windows cant detect trend micro titanium and I cant even open trend micro titanium ...

Regarding the virus, I have no idea where does it come from since most of the time my brother is using it. I certainly not hope to format my laptop as it may be very troublesome ...

These are 3 methods provided by microsoft, none of them worked

Method 1: Scan for malware.
If you haven't scanned your computer for viruses or malware recently, it is strongly recommended you do so. You can use the Microsoft Safety Scanner to remove malware from your computer. To do this, follow the steps below:

Go to: Microsoft Safety Scanner - Antivirus | Remove Spyware, Malware, Viruses Free

Click Download Now. Follow the on screen instructions to download and install the Microsoft Safety Scanner. When prompted, save the file to your desktop.

After installation, go to your desktop and double click the Microsoft Safety Scanner icon. It may be listed as msert.

Click the box next to Accept all terms of the preceding license agreement, then click Next.

Click Quick Scan, then click Next.

The Microsoft Safety Scanner will scan your computer and remove all malware.

Click the Start button, then type Windows Firewall in the Search programs and files box (Windows 7) or in the Start search box (Windows Vista).

Click Windows Firewall.

In the left hand pane of the Control Panel, click Turn Windows Firewall on or off.

Click Turn on Windows Firewall for each network location, then click OK.

If you still receive error 0x8007042c when attempting to turn on your Windows Firewall, proceed to Method 2.

Method 2: Start the Windows Firewall Services manually.

You can start the Windows Firewall services manually as well as make sure it starts automatically in the future. To do this, follow the steps below:

Click the Start button, then type Services in the Search programs and files box (Windows 7) or in the Start search box (Windows Vista).

Right-click Services. Note: there will be a cogwheel located next to it. Then click Run as administrator. If prompted, enter your administrator user name and password, then press Enter.

Scroll until you see Windows Firewall. Double click Windows Firewall.

Click the drop down menu next to Startup type, then choose Automatic.

Under Service status, if it is listed as Stopped, click Start.

Click Apply, then click OK.

Scroll until you see Base Filtering Engine. Double click Base Filtering Engine.

Under Service status, if it is listed as Stopped, click Start.

Click Apply, then click OK.

Restart Windows. Windows Firewall should be enabled.
If you still receive error 0x8007042c when attempting to turn on your Windows Firewall, proceed to Method 3.

Method 3: Start associated services manually.

You can start the following services manually:

Windows Firewall (MpsSvc)
CNG Key Isolation (KeyIso)
Base Filtering Engine (BFE)
Firewall Client Agent (FwcAgent)

To do this, follow the steps below:

Click Start, type Notepad in the Start Search box (Windows Vista) or the Search programs and files box (Windows 7), and then click Notepad in the programs list.
Highlight the following text, right click the highlighted text, and then click Copy. Go to Notepad, right click anywhere in the Notepad window, and then click Paste.



Code:
sc config MpsSvc start= auto

sc config KeyIso start= auto

sc config BFE start= auto

sc config FwcAgent start= auto

net stop MpsSvc 

net start MpsSvc 

net stop KeyIso 

net start KeyIso 

net stop BFE 

net start BFE 

net stop FwcAgent 

net start FwcAgent
Click File, click Save As, and then type Repair.bat in the File name box.

Click the Save as type dropdown, then click All Files (*.*).

In the left window pane, click Desktop, and then click Save.

On the File menu, click Exit.

From your Desktop, right click the Repair.bat file that you saved in step 5, and then click Run as administrator. This action starts the required services.
Note If you are prompted for confirmation, click Yes.

Try to start the Windows Firewall again. If you can start Windows Firewall, delete the Repair.bat file. To delete the Repair.bat file, right-click Repair.bat, click Delete, and then click Yes.

Hi Golden,

this is the result of Microsoft Safety Scanner

1. Trojan:Win64/Sirefef.B - partially removed, restart required
2. Worm:Win32/Gamarue.D - partially removed, restart required
3. Trojan:Win32/Ontonphu.B - removed


I'm sure that after I restart, windows will be unable to start and will lead me to startup repair ... Even startup repair cant solve this.

Hope u can help ...
