What this programs does:
Personal Defender 2009 is a rogue anti-spyware program that
uses Trojans and fake advertising to convince you to install their software.
This rogue is promoted via a Trojan that has a filename of mupd1_2_1711951.exe
and when installed on your computer will display a fake Windows Firewall Security
Alert on your computer. This alerts pretends to be a Windows Firewall alert
stating that the Trojan-Keylogger.WIN32.Fung is running on your computer and
if you would like to enable protection. If you click on the Enable Protection
button you will be brought to a page stating that you should download and install
Personal Defender 2009 in order to protect yourself. These alerts, though, are
fake and are only being shown to scare you into thinking you are infected. If
you just deleted the mupd1_2_1711951.exe file, the alerts would no longer appear.
Once Personal Defender 2009 is installed on your computer, it will be configured
to run automatically when you logon to Windows. Once running, it will conduct
a scan of your computer and list a variety of malware that cannot be removed
unless you first purchase the software. The malware it finds, though, are either
fake or the Trojans that it installed it in the first place. Instead of purchasing
the software, we suggest you follow one of the two guides listed below in order
to remove this infection for free.
