So I recently got infected by a trojan and I couldn't start MS Security Essentials. So I panicked and downloaded the free version of avira and avast anti virus. I first ran avira and it told me that I was infected with the virus TR/ATRAPS.Gen2. After the scan, I put the virus under quarantine (the same virus was in multiple locations). Then I ran avast just to re-check and there were no viruses. So I removed avast (couldn't remove avira..need to check online for that). Then I uninstalled and re-installed security essentials. Now SE is running but windows firewall and defender are not
I searched online and came across a couple of solutions. This is what I did to try to get firewall and defender to run:
1. In services, 'Base Filtering Engine' was missing, so downloaded the registry key online and started the service
2. Downloaded the registry keys for both windows firewall and windows defender
3. Tried to start windows defender service manually from services.msc. This is the error message I obtained "Windows could not start the Windows Defender Service on Local Computer. Error 126: The specified module could not be found"
4. Similarly, when I try to start windows firewall manually, the error message is "Windows could not start the Windows Firewall on Local Computer. Fore more information, review the System Event Log. If this is a non-Microsoft service, contact the service vendor, and refer to service-specific error code 5." (Not sure how to go to the System Event Log, so cannot copy the log here )
I downloaded the SecurityCheck utility and pasting the output below:

Please let me know how to resolve this. I am hoping this gets solved without having to install windows all over again.
Any help would be greatly appreciated
