Let me tell you that the windows update service disables along with any other antivirus software and at one point the service was gone completely. At least I was able to get in and then back out via the internet, otherwise I'd be in trouble since they live several states away.
I won't bore you with the rest of what was next because there was a lot of trial and error, but basically I pulled resources from these web sites. I did finally get Malware bytes installed and we were looking good.

Once that was complete, I got Microsoft Security Essentials installed. And then I moved onto the automatic update issue.
This error came up as well "net start wuauserv the service name is invalid", more research revealed this script.
net stop bits
net stop wuauserv
regsvr32 /u wuaueng.dll /s
del /f /s /q %windir%\SoftwareDistribution\*.*
del /f /s /q %windir%\windowsupdate.log
regsvr32 wuaueng.dll /s
net start bits
net start wuauserv
wuauclt.exe /resetauthorization /detectnow
As of last Thursday we are up and running and work can be continued without reloading this PC. Quite frankly, I wouldn't have spent this much time on one of my personal PCs, but was very glad to help.
Moral of this story: Don't download software that you don't know from whence it came.
