Personal Defender 2009 – Removal Instructions

Personal Defender 2009 is one more, in a long line of rogue security applications currently circulating on the Internet, seeking out unaware users in order to steal their money.

Like all rogue security applications, Personal Defender 2009 is a master at using Trojans, and fake advertising, to convince unaware Internet users to install this parasitic application.

I’ve learned that in this particular case, the Trojan mupd1_2_1711951.exe once it has infiltrated a system will produce a false Windows Firewall Security Alert on the infected computer. This alert is crafted in such a way as to entice the potential victim to download and install Personal Defender 2009 on their system.

If you’re an experienced computer user, then you’re aware that the Internet is saturated with rogue security programs like Personal Defender 2009, which, if installed, can often cost the unfortunate victim loads of money in an attempt to get rid of it. What you might not be aware of is, rogue security software, has now evolved into a billion dollar criminal enterprise.

In the last year, or so, I have heard some horrendous stories from readers where the common thread has been the debiting of their credit cards, multiple times, by the cyber-criminals responsible for the distribution of Rogue Security Software.

The objective of Personal Defender 2009, which is the objective of all Rogue Security Software, is to convince the victim to pay for the “full” version of the application in order to remove what are, in fact, false positives that this program is designed to display on the infected computer in various ways, including fake scan results, pop-ups and system tray notifications.

Like many parasitic applications, this particular rogue security software’s installer is often found on adult websites, or it can be installed manually, from rogue security software websites including www.defender2009.com.

Rogue Security Software unfortunately, is generally very sophisticated and can write itself into multiple parts of the operating system, and in many cases, it can hide its files, registry entries, running process and services, making the infection difficult to find, and extremely difficult to remove.
