BleepingComputer.com: Google files and folders--Should I delete them?

I've seen several people on this forum complain about having Google viruses and issues. So I got curious and decided to do a search on my hard drive to check and see if I still had anything related to Google saved on my hard drive. When I first purchased my laptop, there was a Google desktop installed, but I un-installed it because I choose to use a different toolbar instead.

So after I did the search on my hard drive for anything Google-related, a bunch of Google folders came up in the list. I even see several Google desktop and Google toolbar folders, even though I un-installed that during the summer when I first received my laptop.

Why are all these Google files and folders still on my hard drive? Are they there for a reason? Do I need to keep them there or is it safe to remove them? What would happen if I delete them? Here's a screen cap of the list of Google files and folders that came up in the search below...

Using the Add or Remove Programs may not always remove all traces of certain application, and that is what this looks like. You can try right clicking of these and delete them, you may need to boot into Safe Mode in order to delete these. These will be sent to the Recycle Bin, to totally remove these you will need to delete them from the Recycle Bin.
