lol i used to work in a call center for a now-bankrupt OEM PC company, doing like tech support for residential customers. it was so funny how many people had installed this on their computer, hated its presence, could not get rid of it, and were constantly being terrorized by its fake alerts. i don't know what percentage of total national call volume it generated to support lines during its heyday, but if it was more than 20% i would not be surprised.
