Security Defender is a phony security application that appeared online in February 2010. Security Defender is part of a scam, in which the creators and distributors of this infection hope to profit from attempts at convincing people to pay for Security Defender by tricking them into thinking it is actually security software. Security Defender is also known as Security Defender 2009, and it is very similar to related rogue security programs WinSecurity Defender and Windows Police PRO.

How Security Defender Gets in a PC and What Does it Do?

There are really two modes of infection with Security Defender. In the early days of the parasite, in particular, there were a significant number of infections as the result of people voluntarily downloading Security Defender, believing it to be real software. At the time, Security Defender was being promoted through banner advertisements and malicious sites, which claimed to be selling Security Defender as actual anti-virus software.

More commonly, especially now that Security Defender has been around for a while, the infection is the work of a Trojan. In particular, Security Defender is reportedly associated with a Trojan called Braviax. As is the case with almost all Trojans that support rogue anti-virus software, this Trojan is most frequently hidden in files that are downloaded, and these can be anything from fake video codecs to pirated files on file sharing sites. Once the Trojan finds a way to get a foot in the door, it will make sure Security Defender is installed and set up. The next time you boot Windows, Security Defender will be there, thanks to some changes in the registry.

Other common symptoms of a Security Defender infection include:
  • Frequent fake system scans, especially after Windows starts, from a fake home screen interface.

  • Lists reports of fictitious scan results that include many severe threats, none of which actually exist on the system.

  • Pop-up warnings that claim that threats have been detected, with prompts to “clean the system” by buying Security Defender.

  • Inability to access the Internet, or extremely limited Internet access.

  • Sudden appearance of Security Defender shortcuts in multiple locations.

  • Slow computer performance, due to Security Defender consuming system resources.

Security Defender can be extremely disruptive and annoying. Just remember that you cannot trust the things it tells you, and that Security Defender is a threat, not the answer to a threat. Paying the money for the bogus activation of Security Defender isn't worth it, either, since it cannot be activated because it isn't real software. Paying up will not get this rogue security program to leave you alone. You can remove Security Defender from your computer, and make sure you do not cave to the con-artists behind this malware.

To check your computer for Security Defender, download SpyHunter Spyware Detection Tool.

Detection of Security Defender (Recommended)

Security Defender is difficult to detect and remove. Security Defender is not likely to be removed through a convenient "uninstall" feature. Security Defender, as well as other spyware, can re-install itself even after it appears to have been removed.

You also run the risk of damaging your computer since you're required to find and delete sensitive files in your system such as DLL files and registry keys. It is recommended you use a good spyware remover to remove Security Defender and other spyware, adware, trojans and viruses on your computer.

Run a Security Defender scan/check to successfully detect all Security Defender files with the SpyHunter Spyware Detection Tool. If you wish to remove Security Defender, you can either purchase the SpyHunter spyware removal tool to remove Security Defender or follow the Security Defender manual removal method provided in the "Remedies and Prevention" section.

Method of Infection

There are many ways your computer could get infected with Security Defender. Security Defender can come bundled with shareware or other downloadable software.

Another method of distributing Security Defender involves tricking you by displaying deceptive pop-up ads that may appear as regular Windows notifications with links which look like buttons reading Yes and No. No matter which "button" that you click on, a download starts, installing Security Defender on your system. Security Defender installs on your computer through a trojan and may infect your system without your knowledge or consent.

If you think you may already be infected with Security Defender, use this SpyHunter Spyware dectection tool to detect Security Defender and other common Spyware infections. After detection of Security Defender, the next advised step is to remove Security Defender with the purchase of the SpyHunter Spyware removal tool.


Security Defender may attempt to change your computer's desktop, hijack your browser, monitor your Internet browsing activities, change system files, and can do this without your knowledge or permission. Therefore, it is strongly recommended to remove all traces of Security Defender from your computer.

Remedies and Prevention
