Trojan Win32.Sirefef is a malicious bot trojan family that uses security exploitation to drop other viruses and spyware onto compromised local and network machines. Usually, Win32.Sirefef opens a security backdoor which allows remote attackers access to upload and activate further malware on the system. The Win32.Sirefef trojan may also monitor users browsing activities and transmit sensitive personal information like banking data and passwords to outside hacker websites. Win32.Sirefef is usually distributed through corrupted e-mail attachments, IRC, P2P and social networks. It may also spread via malicious drive-by downloads installed onto hacked or malware websites

Be sure you change ALL passwords using a known 'clean' machine ... not the infected one.

Windows 7 Firewall Error 0x8007042c

Error code 0x8007042c is an error for "The dependency service or group failed to start".
This will indicate that there may not be a problem with the Windows Firewall Service (MpsSvc) but instead with other Services that it needs so that it can start itself.
So here are the necessary Services that Windows Firewall needs on Windows 7:
1. Base Filtering Engine (BFE)
2. Windows Firewall Authorization Driver (MPSDRV)

The two services/drivers should be started or running. BFE can be easily seen through the Services Console. But MPSDRV is not visually available in the same console window and instead available only by querying the service in a Command Prompt window.
Repairing services and drivers can be done via the command line of SFC /SCANNOW on an Elevated Command Prompt.

If the command did not fix the issue then reinstalling the drivers might be the best way to do it.
Although to accomplish this will not be an easy feat since both the Base Filtering Engine and Windows Firewall Authorization Driver could not be reinstalled on Windows 7 unless we repair install the Operating System.
Try running the following commands if SFC /SCANNOW did not resolve the issue with the Windows Firewall:
1. Open a Command Prompt as Administrator. To do this, type CMD in Start Search from the Start Menu. Right click on the result and choose "Run as Administrator".

2. Run now the following command lines:

a. netsh advfirewall reset
b. net start mpsdrv
c. net start bfe
d. net start mpssvc
e. regsvr32 firewallapi.dll
3. Confirm any boxes that comes up by clicking OK. The result on the last entry should say that it succeeded.
Note: If you receive any errors on any of the command lines, then there is definitely something wrong with any of the drivers and service. This may indicate a Registry error or a Corrupted file.
4. Reboot the system.

@Simcut: Which cmds failed?

--> edit: Did SFC report anything?

-->edit: @Jacee: I'm not that familiar with all of the command line utils, but what you posted looked weird and neat. I wondered can you execute all of that on one line? The answer is nope. Between MS and Seven forums - the difference btwn cr/lf - yours and subsequently my own copy / paste joined the lines. I notice the link back to MS before I posted Jay Pilarta's information. anyway, it seems as though the MS information is the better bet - Thanks.

Sorry, just saw Jacee's post refered to a Ms page.

Try the batch attached. RepairWinFire.bat

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 start Wlansvc
net start dot3svc
net start EapHostnet
net stop BFE
net start BFE
net start PolicyAgent
net start MpsSvc
net start IKEEXT
net start DcaSvcnet
net stop FwcAgent
net start FwcAge


Run in elevated command prompt

If you still receive error 0x8007042c when you try to start Windows Firewall, you may want to contact Microsoft Consumer Security Support Center. To do this, go to https://consumersecuritysupport.microsoft.com.

I'm glad I was able to get the batch file squared away for you, but I think that's about as far as I can help. Other folks around here have more knowledge and experience on the correct command line utils than I do. It may very well end up beinr a repair install, or someone else might suggest the one command that will get you over the hump.

Last thing from me - have you restarted?

Good luck. sorry I couldn't help more.

Simcut,

Under the circumstances, I'm going to recommend what I call a 100% clean install which means:
1. Backup any data dear to your heart
2. Use DiskPart and its CLEAN ALL command to write zeroes to each and every byte on your hard disk.
That will get rid of anything evil on your computer.
3. Install Win 7 using your Win 7 DVD/usb stick.

here are a couple of tutorials which will help you.
Disk - Clean and Clean All with Diskpart Command

Clean Reinstall - Factory OEM Windows 7

And immediately after that:
1. install MSE
2. update 100% your Win 7
3. Never use any P2P software, such as BitTorrent, VUZE, µTorrent
4. Don't visit questionable sites such as porn sites. Use WOT.
