PC Defender 360

Also Known As: PC Defender 360 Rogue
Damage level: High

What is PC Defender 360?

PC Defender 360 is a rogue antivirus program created by cyber criminals. The main purpose of this fake security scanner is to scare unsuspecting PC users into believing that their computers are infected with high-risk malware, and then encouraging them to purchase a useless program.

This bogus program infiltrates users' computers using 'exploit kits', which are proliferated using infected email messages, malicious websites, and drive-by downloads. After successful infiltration, PC Defender 360 imitates a genuine antivirus program by starting a fake security scan.

After a few minutes, the rogue program generates a large list of supposedly-detected malware and viruses and demands payment for the full version of the program, which purportedly eliminates the 'detected' security threats. In fact, none of the detected security infections exist - PC Defender 360 is a scam, which attempts to trick PC users into buying the 'full version'.

PC Defender 360 rogue program

This fake antivirus program imitates the detection of identical security infections on each computer infiltrated. The rogue security program originates from a family of fake antivirus programs called FakeRean. Note that a previously-discovered variant from this family was named Antivirus System.

If you observe PC Defender 360 scanning your computer for security infections, your PC is infected with a rogue antivirus program. Do not trust it or pay for the full version, it is a scam.

PC Defender 360 adopts a professional-looking user interface, however, this is its only similarity to legitimate antivirus programs. This software is a scam, since it has no virus definition database or virus scan engine - it simply relies on fake security scans and false security warning pop-ups in order to trick PC users into buying the 'full version'.

Note that buying this program is equivalent to sending your money to cyber criminals, and moreover, by purchasing this scam, you will divulge your banking information, which could lead to further thefts from your account.

If you have already paid for PC Defender 360, contact your credit card company and dispute the changes, explaining that you have been tricked into buying a fake antivirus program. To remove this scam from your computer, use the removal instructions provided.

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.
