Iron Defense is a rogue antispyware program that infiltrates into computer systems via Trojan viruses
. It is promoted through pop up ads and various security notifications that appear on the screen without a reason stating that your computer is badly infected. They also offer performing system scan online. Once you click on the notification, it will redirect you to the website offering online scanner. Later on it will attempt to prove you that you need to install IronDefense into your computer.
Beware that it doesn't actually scan your computer but only imitates the action. Instead of giving a valid scan results, IronDefense generates a list of random files of your legitimate programs of files that doesn't exist on your system at all. Basically the program displays anything just to create an illusion your computer is infected. The next step is to make the user purchase a so called full version of Iron Defense. The application states that infections can only be removed with this version of the program. However, if you pay for it, the situation remains the same but your credit card is being charged.
Please do not trust IronDefense application under any circumstances. Though it looks like a legitimate antispyware program it has nothing to do with it and was only created to rip computer users off easily. You are strongly advised to get rid of IronDefense as soon as you notice it on your computer. Don't forget to run a full system scan regularly with a legitimate tool.
