I volunteer at a church by helping out with some basic IT issues from time to time. I recently had to disable Chrome browser notifications on one of their PCs because the McAffee anti-virus notifications just wouldn't stop. I thought I had already uninstalled the actual McAffee desktop software but I guess it embedded itself into the chrome browser somehow too.

On a related note, I wish Chrome had an easy way to permanently say "don't ask again" (on a site-by-site basis) to the "Do you want to login with a google account?" popup that so many sites have nowadays.
