When ever you install one of many of Google’s application, such as Chrome or Picasa, a smaller GoogleUpdate.exe is installed.
Googleupdate.exe uses nearly 1.8 meg of memory while running. The application is installed as a part of a task scheduled service that checks for updates for its software, but with the nefarious cavet, it also sends data to Google’s servers when ever it checks for updates.
To disable Googleupdate.exe open the services configuration with Windows Key+R, Type in Taskschd.msc and press enter. The Task is called Google Update Service (gupdatexxx) with xxx being a random ID)
Right click on GoogleUpdate.exe will open the properties of the services with the option and choose Disabled.
