Don't feel bad, man, at least you bought the stuff. I signed up for the free trial, decided it was a tad high, canceled the renewal.
That was a month ago. Still getting the "YOUR ANTI-TRACK SUBSCRIPTION HAS EXPIRED" pop ups every. single. day. At least once, usually several times a day, overriding my notifications settings, overriding game mode, often in a nonmodal form that has no X to cancel out. Somewhat urinated off to see the obnoxious thing pop up between me and the dragon I was handily slaying until someone pasted a GIANT RED SQUARE over my eyes.
I'd love to support them, frankly, but last time I broke down and bought the AV they started with the nonstop pops immediately, and abused their system privilege to the point of utter rudeness and beyond. I never have this kind of idiocy occur if I just stick to the free antivirus and never touch anything else. I must remember that next time I am tempted to try one of these a la carte app fragments.
