Virus deleted some of my Services...Now what?

I recently had a few viruses on my laptop. I've got them removed but found that my Windows update, firewall, Windows Defender, and who knows what else, wasn't working because some of my Services were deleted. I have managed to get WU and Defender working but not the firewall. Is there a place where I can download all the Windows 8 services reg files in a single batch file? Thanks
