Strong Malware Defender

Also Known As: Strong Malware Defender Rogue
Damage level: High

What is Strong Malware Defender?

Strong Malware Defender is a misleading program derived from a family of rogue applications such as AV Security Essentials, Smart Antimalware Protection, Antivirus Smart Protection, and many others. Internet criminals use a similar interface to Microsoft Security Essentials (a legitimate free antivirus program) for their latest rogue program called Strong Malware Defender.

This rogue security scanner is proliferated by large malware networks operated by Internet criminals. Their attacks include various methods of computer infection such as misleading website creation, search engine result poisoning, spam campaigns, etc.

Do not mistake Strong Malware Defender for a legitimate security program - it is useless software created with the intention of selling you a fake license.

When Strong Malware Defender infects your computer, it instantly starts an imaginary security scan, and in this way, attempts to scare you into believing that your computer has serious security issues and that this rogue program is the only method possible to remove them.

Ignore the detection list of high and critical security vulnerabilities displayed by Strong Malware Defender. This program has no crucial components required of a genuine security suite - Strong Malware Defender simply imitates the computer security scan and the detection of numerous spyware, malware, and Trojans on your PC.

After clicking the 'Remove All' button in Strong Malware Defender, you are redirected to a website asking you to purchase a license for this program to remove the 'detected' security threats. Therefore, purchasing Strong Malware Defender is very ill advised; this program is a security threat in itself.

Purchasing a license for Strong Malware Defender will not solve your problems, only worsen them - your computer will remain infected and your banking information will be at risk. If you have bought Strong Malware Protection, contact your credit card company and dispute the charges.

Always carry out research prior to buying a security program for your PC, as today, the Internet is flooded with fake antivirus programs such as Strong Malware Defender. Use this removal guide to completely remove Strong Malware Defender from your PC.

4. Download HijackThis and save it to your desktop. Some malicious programs are able to block HijackThis, so when you click the download link, in the Save dialog, rename HijackThis.exe to iexplore.exe and only then click the Save button. After saving the file to your desktop, double click it. In the main HijackThis window click the “Do a system scan only” button. Select the following entry (place a tick at the left of the entry):

O4 – HKCU\..\Run: [Strong Malware Defender] “%AllUsersProfile%\\_.exe” /s /d

After selecting the required entry, click "Fix Checked". After this procedure you can close HijackThis and proceed to the next removal step.

5. Download legitimate anti-spyware software to fully remove Strong Malware Defender from your computer.

6. After removing Strong Malware Defender, reset your Hosts file. Do not skip this step, since this malware modifies your Hosts file and you will encounter browser redirect problems.

The Hosts file is used to resolve canonical names of websites to IP addresses. When it is changed, the user may be redirected to malicious sites, despite observing legitimate URLs in address bar. It is difficult to determine if the site is genuine when the Hosts file is modified.

To fix this, please download the Microsoft FixIt tool that restores your Hosts file to the Windows default. Run this tool when downloaded and follow the on-screen instructions. Download link below:

Summary:

The fake antivirus programs (also known as "rogue antivirus programs" or "scareware") are applications that tries to lure computer users into paying for their non-existent full versions to remove the supposedly detected security infections (although the computer is actually clean). These bogus programs are created by cyber criminals who design them to look as legitimate antivirus software. Most commonly rogue antivirus programs infiltrate user's computer using poop-up windows or alerts which appear when users surf the Internet. These deceptive messages trick users into downloading a rogue antivirus program on their computers. Other known tactics used to spread scareware include exploit kits, infected email messages, online ad networks, drive-by downloads, or even direct calls to user's offering free support.

A computer that is infected with a fake antivirus program might also have other malware installed on it as rogue antivirus programs often are bundled with Trojans and exploit kits. Noteworthy that additional malware that infiltrates user's operating system remains on victim's computer regardless of whether a payment for a non-existent full version of a fake antivirus program is made. Here are some examples of fake security warning messages that are used in fake antivirus distribution:

Computer users who are dealing with a rogue security software shouldn't buy it's full version. By paying for a license key of a fake antivirus program users would send their money and banking information to cyber criminals. Users who have already entered their credit card number (or other sensitive information) when asked by such bogus software should inform their credit card company that they have been tricked into buying a rogue security software.
