Process started by GoogleUpdate.exe and was distributed by Google until about 2011. While not malicious, it is no longer supported by Google and is unnecessary. All it represents now is a potential attack surface. I recommend removing it.

I am in the habit of watching task manager as my computer boots up, and manually "End Process Tree" when Google updates start to load, since obviously not required every time. This is the first time I've noticed GoogleUpdateCore.exe, which is almost instantly replaced by GoogleUpdate.exe on Task Manager. I will look into the precautionary recommendations from to check out my Sys32 folder, and delete this if possible. I certainly cannot afford and extra 599,632 bytes on my system at any time. I would never knowingly authorize any update to the Core processes - because of the need to keep XP space available for the applications of my choice, as well as safe and secure. The only outside request I have authorized was when Microsoft was finally forced to make a security update for XP a couple of months ago. Previously, I have been watching a 2nd rundll32 which only showed up recently running simultaneously. It arrived after a major servicing to reclaim my CPU space & not be forced to discard my P4 & XP system, and with the assistance of Intel & Mcafee Live. I concluded this new 'on again-off again' rundll it was performing an update function and did not relate to any virus or trojan-like behavior. Eventually it stopped showing up and uses less time and less space when it does return. Could this rare rundll32 appearance be connected to the GoogleUpdateCore.exe -- ?
