Defense Center is a rogue anti-virus program, which means that it is at the heart of a scam, designed to steal your money by infecting your computer with a malware infection and trying to convince you that the infection is real software that you need to pay for. Defense Center is almost identical to rogue security applications Dr. Guard, Your Protection, My Protection, User Protection, Data Protection, Paladin Antivirus, and Digital Protection. It's the same scam; it just gets renamed and updated every few months. Defense Center (sometimes appearing as Defence Center) is the version of this infection that appeared in June 2010, possibly growing more malicious than before by July.

How Defense Center Infects a Computer

Defense Center is installed onto a computer by a Trojan, and the Trojan is hidden online in places that you will not suspect, so that it can take advantage of vulnerabilities in your computer system or hide in a file that you will download without thinking. There are also a few websites that host a phony free "scan" which actually infects your computer, and some of the known sites are traffic-photos.com, easysecurityscan.com and fastanyprime.com. The Trojan may cause pop-up warnings that urge the purchase of Defense Center before the Defense Center infection is present, in order to lure you into downloading the infection, or the Trojan may simply download Defense Center on its own. Either way, once the Trojan changes some settings in order to make sure that it runs whenever Windows runs, the next time you boot the system, you will not be able to ignore Defense Center.

Once Defense Center has installed on your computer, it can have these symptoms:

  • Fake home screen shows when Windows starts, and Defense Center runs a fake scan with fake scan results. You will be prompted to buy the "full version" to remove the detected threats.

  • Frequent pop-up warnings from the system tray, which mention remote attacks and scary-sounding viruses.

  • All other programs are prevented from opening.

  • Defense Center tries to uninstall your actual anti-virus software, or to scare you into doing it by claiming the real anti-virus software is infected.

  • Internet Explorer may redirect to Defense Center's bogus sites when you try to go online.

  • Pop-up ad advertising "one day sale" offer to get Defense Center at 30% off.

  • Links to pornographic websites are created on the desktop.

  • Task Manager is disabled.

As an added nasty bonus, Defense Center sometimes has a rootkit bundled with it, which is called RootkitTDSS. RootkitTDSS can cause your web searches to redirect to malicious websites that may cause further infections. Overall, Defense Center's activity may consume a significant amount of system resources and cause your computer to run unusually slowly.

It is important to remember that the crooks who created Defense Center have engineered the entire frustrating experience that you have when this infection takes over your computer. You see what they want you to see, and are limited to doing what they want you to be limited to doing. The goal is to manipulate you into paying money for a "full" version of Defense Center, when there is no full version, because Defense Center isn't capable of providing any security. Don't pay these criminals for what they have done, and do not let them mislead you into believing that your PC is a lost cause, and you are not able to do something about your computer's state.
