The only thing I dislike about Apple forums is the seemingly incessant need to be "right"... rather than to simply ... "help." Back in March I posted images of what I referred to as Adware, when I should have stated they're an indication of... a PART of the process of adware being placed on your system.
The whole point of those crummy pop-up's are two fold;
(1) They do and can initiate the implementation of adware by first locking you out of being able to use your browser, requiring you only one option (to the layman) and that's to click one of their buttons. And at the very least, you get stuck with crummy tracking cookies and more.
(2) The second aspect and purpose of the images I posted are to trick people into calling the bogus 800 number, where upon the person you speak with takes you through a couple of steps to remove any firewall protection, gain your MAC info (machine address) and more - there by gaining access to your computer. I personally know because I called the idiots just to see what they were trying to do to people.
I especially despise the misleading statement... that if you're already panicking after reading your computer may have serious issues - when you read, "please call support for Apple"... one might first think they're contacting Apple Support. It just deviously rolls off the tongue so easily - "Support for Apple."
I've personally had MacKeeper misleadingly (basically) auto install (without permission) on my computer when I thought I was downloading an extension for a browser. I didn't even know it was installing, and by the time I realize it - I couldn't stop it. And to top it off - they have an immediate ability to take control of your computer, or at the very least, be able to see everything. I also consider and call these types of actions, virus, malware, adware, trojans, and consider all their tactics and ethics no better than that of hackers.
I question any validity or claim of knowing ANYONE that's actually been sued by Zeobit / MacKeeper. I might believe someone may have been threatened, but even a threat doesn't necessarily carry any weight. I question this because I know they have a class action lawsuit currently pending that we're participating.
