I don't care for Google Updater software.

I used Chrome for a search and ended up with the notice (“GoogleSoftwareUpdate.bundle is an app downloaded from the Internet. Are you sure you want to open it?”) on my desk top. See screen shot below.
I hit cancel several times, but it just pops back up. I shut down the computer then started up again and it still pops up. Any suggestions? Should I just “open”?
I think I may decide to never use Chrome again… not the first trouble I have had using it.

So the google software updater is a file that is asking permission to be installed. It's main job is to ensure that Chrome is up to date. It was brought in by you either using Chrome or Google Earth. I personally don't want that running on my system because it's more invasive than just that. Remember that first and foremost, Google is an advertising company so any information they can glean from your computer habits have the potential to be monetized. The problem is, once you've allowed it to install, you'd have to know where to look to remove the startup files. Otherwise it will keep coming back. Even when you do clean it out, if you run Chrome in the future, you'll just be presented with the same item again eventually.
