Major Defense Kit

1 November 2010 

Major Defense Kit - Finding a Better Security Kit

Virtually everyone who owns a computer these days understands the importance of defending it against potential threats, and there are so many great software programs out there that can help with that. These days, though, there are several programs that seem like legitimate solutions to potential security threats that, in truth, are not. Dubbed rogue antispyware, programs like these are designed to make you believe you have a number of different infections on your machine so you'll purchase and download the full version of the program. Major Defense Kit is one such program.

Faking Windows Security Essentials

Over the years, Windows Operating Systems have continually updated the interface and security features to help users stay away from problem programs. Unfortunately, however, many rogue antispyware solutions have mimicked their tactics, and that's the case with Major Defense Kit too. What looks very much like a Windows Security Essentials alert. Across the top, it even says "Microsoft Security Essentials Alert." From there, you'll see a red bar across the top of the warning that says "Potential threat details." It goes on to say that the program has detected "potential threats that might compromise your privacy or damage your computer. Your access to these items may be suspended until you take an action. Click ‘Show details' to learn more." The files shown as detected are "Unknown Win32/Trojan" and the threat level is shown to be severe. You are given a number of options, including "Apply Actions" and "Clean Computer." Clicking on either, however, will result in a message that says "Unable to Remove Threat." From there, you're given a choice to "Scan Online" and clicking on that choice offers you a number of different antivirus scanners. All of the ones that suggest they found a Trojan Horse and have free installation are clones of Major Defense Kit. The clones listed include:

  • AntiSpy Safeguard
  • Pest Detector
  • Peak Protection
  • Red Cross

Clicking on these, naturally, installs a Trojan that further installs Major Defense Kit.

Major Defense Kit - A Few Things You May Notice

If you do have this program installed on your computer, there are a number of different things you will notice right away. One of the first is automatic scanner. Before your Windows screen ever actually has a chance to boot, the scanning window will, and it will give you a list of files installed on your computer that it "found" during its scan. The window itself has a blue background and across the top is a menu bar with options like Scanner, Privacy, and and Support.  Across the bottom there are three different scan options as well. All of the files found, the program will tell you, are infected, and none of them can be repaired until you use the program's heuristic mode. You cannot, however, access this mode until you've purchased the full version of the program. It's important to note, however, that none of the infections are actually present on your machine. What's more is that buying the full version of the program won't actually remove any of the problems or even the messages that you're seeing. The program simply isn't designed to deal with any possible threats, so making the purchase won't help you further protect your machine.

In addition to the scanner, you may also notice that some programs shut down before they ever really get started. Major Defense Kit has the ability stop a computer program before and after you've actually clicked on it, and it will then display a message that the program is infected. The text of the message typically reads:

The application was launched successfully but it was forced to shut down due to security reasons. This happened because the application was infected by a malicious program which might pose a threat to the OS. It is highly recommended to install the necessary heuristic module and perform a full scan of your computer to exterminate malicious programs from it.

Moreover, some computer processes may be blocked on your computer as well. Things like Safe Mode may no longer be accessible to you. Processes like Task Manager and Registry Editor are similarly inaccessible if Major Defense Kit has been installed on your machine.

Removing Major Defense Kit

If you wish to remove Major Defense Kit, there are essentially two different options - manual removal or eliminating the program with a software security solution. Many believe that it may be possible to remove the program with their current antivirus software. This, however, is not the case. Major Defense Kit is rogue antispyware, and it doesn't have the properties of any ordinary virus. As a result, the virus definition files your antivirus solution uses simply aren't equipped to deal with this program, so you can't rely on it to help you with your problem.

Perhaps the strongest solution is to download and install a reputable antispyware solution. There are a number of different options on the market today, but two of the best options are Malwarebytes Anti-Malware (Malwarebytes has free malware removal) and Enigma's SpyHunter. After you have finished the installation process, you should update the definition files, then set the program to scan your computer. Doing so will eliminate the program automatically from your system.

Your other option is to remove Major Defense Kit manually from your system. If you do so, however, keep in mind that it can be a bit risky. If you're a novice or you don't have a solid level of technical experience, you may want to contact us for additional information and detailed instructions. There is a list of registry keys and files that should be deleted after this article. Keep in mind that you will have to set your computer to show all of the hidden files and folders so you can eliminate all traces of the program. You can do that by clicking on the Windows Explorer Tools menu, but you should reverse that process after you've finished. Moreover, you may still want to install a good antispyware program to help remove any files you missed or to keep your machine safe from future threats.
