I finally got rid of this I think. The quick work around is to choose "Limited Protection" when that stupid window comes up and then you can go to settings and turn off the start-up launch and prevent it from pinging your wi fi. But I wanted it off my computer. I made sure I was signed in with administrator rights, went to settings, Apps, i right-clicked on it from the list of programs/apps and chose uninstall. I also went through and deleted all the files I could find as the uninstall doesn't completely clean it up. there's still some things I can't delete because "not found", but it seems to be pretty much gone.
I wanted to purchase their virus scan software and accidentally purchased the "free trial" for this; when I realized my mistake I wanted to cancel to avoid charges at the end of the free trial. It took me an hour on the phone (the only way to cancel is by phone) and I finally got it.
These guys suck.
