Then it immediately redirects you to another website, in my case it was free-choice.com.au, where you can choose an Apple product, let's say and iPad or iPhone and try to win it. The trick is that you need to give them your phone number and subscribe for their paid services.
All the information is given below the advertisement in a ridiculously small font size that you can hardly read without using a magnifying glass or text zoom feature. Once they have your phone number and other information they can send you ads or recommend joining other paid services. My advice is to stay away from such websites and do not ever give them your phone number.
This scam targets non-English speaking countries as well. Here's an example of a shuang11huodong.com pop-up in French. It says "Félicitations!!! Vous êtes l'heureux visiteur du jour, éligible pour gagner un iPad!"
So, basically the same thing except that the landing page is prizerally.com for French users. However, the scheme is the same, you need to enter your phone number if you want to participate and contest and win an iPad. Do not do this, because you may later have serious problems unsubscribing from paid services.
Trojan.Clicker.CT is a pretty bad infection. It redirects users to scam websites but can also download additional malware onto your computer. It can also slow down your computer. Besides, just because you are getting "win an iphone 5s" type of ads at the moment it doesn't mean scammers can not redirect you to fake Flash update pages or exploit kits and end up with more malware on your computer. To stop these annoying pop-ups and remove malware from your computer, please follow the steps in the removal guide below.
