Ugh.  Was having some trouble accessing a site I use for work daily (my company and all its employees work virtually).  Kept having trouble but all others did not.  Did a little bit of research and somehow figured out that I might have some type of malware.  I have Microsoft Security Essentials, ran a scan, results....nothing, all is fine.  But was concerned that it had not run a scan in almost a month.  Ended up figuring out that my firewall was not turned on.  Clicked on Update your Firewall Settings, the only option that it gave me was to "Use recommended settings".  When I click on that, it does nothing.  Sometimes it will tell me that it can not do that and ask me to manually do it, sometimes it says nothing and it still says my firewall is not on. Regardless of whether it gives me a message or not, the firewall does not come on.  I've installed Malware Bytes (free) and SuperAntispyware (free), run both, found some issues, got rid of them, shutdown and restarted and still no firewall.  Feeling a little exposed at this point and frustratingly tired....nothing has really worked.  Any suggestions...please....anyone?

If Malware has damaged the Windows Firewall service you can use the command "sfc /scannow" to repair it.

 

I recommend using the boot recovery or safe mode for no interruptions, simply run CMD.exe as Administrator and type in Sfc /scannow

It will take a while so be patient.

 

Alternatively if you have a restore point you can use that.

Try using Windows Repair Tool (All In One) or Windows Repair Portable. This all-in-one repair tool was designed to help fix common Windows problems such as file permissions, issues with Internet Explorer, Windows Update, and Windows Firewall caused by malware infection.

Just run these commads in DosPrompt

Check to see if its running and all values are correct

wmic service where name="MpsSvc" get /all /format:list

Should lookm something liek this mate:

AcceptPause=FALSE

AcceptStop=TRUE

Caption=Windows Firewall

CheckPoint=0

CreationClassName=Win32_Service

Description=Windows Firewall helps protect your computer by preventing unauthorized users from gaining access to your computer through the Internet or a network.

DesktopInteract=FALSE

DisplayName=Windows Firewall

ErrorControl=Normal

ExitCode=0

InstallDate=

Name=MpsSvc

PathName=C:\Windows\system32\svchost.exe -k LocalServiceNoNetwork

ProcessId=1648

ServiceSpecificExitCode=0

ServiceType=Share Process

Started=TRUE

StartMode=Auto

StartName=NT Authority\LocalService

State=Running

SystemCreationClassName=Win32_ComputerSystem

Then run this if it isnt running.

netsh advfirewall set allprofiles state on

That should enable the firewall.

The Windows Repair Tool repairs Windows Firewall by doing most of that automatically.
