I have recently downloaded an update using the Windows Update Auto Update tool on my Windows XP Pro Machine. The update downloaded quickly and so I chose to install it, an alert box popped up from Zone Alrm Pro alerting me that the program wuauclt.exe has changed.

Could this be a virus / trjoan that someone has sent to my PC?

I have serched for a while on the internet and found several pages about wuauclt.exe being a networking component and another page saying it could be a trojan.

I have denied the access for now just on the safe side.
