Security Defender

It can be easy to fall for the surreptitious lies sold as truths by sophisticated and genuine looking rogue security tools such as Security Defender. The problem with these false security tools is that they are completely unable to live up to any of their over embellished promises. Security Defender, a direct clone of Antimalware Defender, is an antispyware application out to rip hard working consumers off. Despite what Security Defender would like its prospective victims to believe, it has no ability to detect, quarantine or remove any type of threat or infection, and is nothing more than an infection in itself.

Security Defender’s infiltration into any system is virtually undetectable. This makes it even harder to identify and get rid of Security Defender. Security Defender makes use of Trojan horses to spread its infections to unwary PCs. These Trojans are distributed through a complex network which includes browser hijackers and fake online malware scanners. These browser hijackers forcefully redirect users to their compromised landing pages and subsequently deliver and root the Security Defender Trojans and malware into their systems.

The first inclination the user will have of Security Defender on his system will be when it reveals itself by spamming the user with various fake security alerts. These alerts were designed explicitly to cause panic in the user, and to place Security Defender in an authoritative light. But once you are to follow the rogues urges to purchase the full version of the program you are greeted by a notification, saying that Security Defender would cost you “only” 79.99 USD, and you will be able to “save” the additional 50 USD. That is obviously false, because once you provide these criminals with your credit card data; they can rip off a lot more.

The rogue does not merit any consideration and users are warned to accept all correspondence received from Security Defender as highly suspicious. It tries to make you believe it is a genuine program by having Softpedia certificate on its purchase page, as well as ZDNest best rating and the insolent Money Back guarantee. All of these notifications are obviously fake. Do not react to any calls to action contained in these false security notifications as this will only serve to make it that much easier for Security Defender to attain its devious goals. Some of Security Defender’s false security alerts to be weary of include the following:

Users who did not get rid of Security Defender in time complained about being unable to connect to the Internet, as well as being unable to launch any program on their PCs. Others complained about increased erratic system behavior and poor system performance. At the end of the day Security Defender will take control of your entire system and hold it ransom until you pay for its fake security software.

If you would like to “activate” Security Defender on the system in order to reestablish your Internet connection as well as the ability to execute programs, paste the following security key into Security Defender:


Do not think by merely entering the above security key that you have successfully gotten rid of the threat on the system. This will only stem the annoying symptoms of this rogue, but you still need to obliterate Security Defender from the system in order to eliminate the threat for good and take back control of your system. Do not waste another second and destroy Security Defender from the system for good.

  29. ccspro Feb 1, 2012

    Add isecurity.exe and privacy.exe to the list of apps

    To manually remove the files (in dos) you may have to "attrib -s -h -r " where is the file you want to remove these attributes from (removes system, hidden and read only)

    In dos to search for these files:
    dir /s /p \*partialname* helps to find non hidden files
    dir /ah /s /p \*partialname* helps to find hidden files

    Good luck!

  30. Pcthreat Feb 1, 2012


    thanks for the tip, although some users (especially amateurs) might find these DOS commands like swearing and is a bit too hard for them.

    As for the two files, They are from other rogue programs infections (isecurity.exe is from internet security 2012). You might have been infected with more that one rogue...

  31. Kevin Jan 17, 2013

    This security key does not work for me. Do you have an updated key?
