How to Remove Internet Defender (Uninstall Guide)

Internet Defender is a rogue security application that runs a system scan for viruses and reports false threats to frighten you into thinking your computer is infected with Trojans, viruses, spyware and other type of malware. The rogue program displays fake security warnings and annoying pop ups stating that your computer is being attacked from a remote machine or that additionally installed software can steal your passwords and other sensitive information. Internet Defender is a piece of malware designed to rip people off. The bad guys behind this rogue program hope that you will believe your computer is badly infected and pay for the full version of the software to clean your PC. Internet Defender impersonates the legitimate Microsoft anti-spyware program called Windows Defender. This rogue AV makes its way to the system with the help of fake online scanners and Trojan horses. It is obvious that Internet Defender 2011 is a complete scam. You shouldn’t install or purchase this scareware. And if you somehow ended up with this malware on your computer, please follow the steps in the removal guide below to remove Internet Defender from your computer for free.



Internet Defender is a clone of Security Defender. We wrote about it two weeks ago. The graphical user interface and self-defense mechanism hasn't changed much. The rogue program uses randomly names files and web browser hijacking to block legitimate security related websites and malware removal tools. Here are some of the fake security warnings it displays:

Internet Defender
Spyware.IEMonster process is found. The virus is going to send your passwords from Internet browser (Explorer, Mozilla Firefox, Outlook & others) to the third-parties. Click here for further protection of your data with Internet Defender.

Internet Defender Firewall Alert
Suspicious activity in your registry system space was detected. Rogue malware detected in your system. Data leaks and system damage are possible. Please use a deep scan option.

Although, it is possible to remove Internet Defender manually, we do not recommend doing so. First of all, it drops randomly named files into ApplicationData (Win XP) and ProgramData (Win Vista/7) folders. It could be rather difficult to identify and delete each malicious file from your computer. Secondly, Internet Defender can download additional malware onto your computer. That's why you should definitely scan your computer with anti-malware software. Last, but not least, if you have already purchased this phony security program, you should contact your credit card company and dispute the charges stating that Internet Defender 2011 is malicious software. If Internet Defender is installed on your computer, you should remove it immediately. Please follow the removal instructions below. If you have any questions or comments for us, please let us know. Good luck and be safe online!
