Antivirus Scan

What is Antivirus Scan?

Antivirus Scan is a malicious program that attempts to imitate a genuine security program. After installation, this fake antivirus software configures itself to run on each system start up.

It then performs a fake security scan and reports that your computer is infected with various spyware, malware, and viruses. These security warnings are fake and this program is created to scare people into purchasing a full version of the software.

The security scans are imitations only, and will not protect your computer.

Do not buy this program, it is a scam. If you have already purchased this fake program, you should contact your credit company and dispute the charges, explaining that you have been tricked into purchasing fake security software.

After Antivirus Scan has infected your computer, the following security warnings may appear on your screen:

“Antivirus software alert. Infiltration alert. Your computer is being attacked by an Internet virus. It could be password-stealing attack, Trojan Dropper, or similar.”
“Windows Security Alert. Windows reports that your computer is infected. Antivirus software helps to protect your computer against viruses and other security threats. Click here to scan your computer. Your system might be at risk now.”

These security warnings are fake. You should remove Antivirus Scan as soon as possible.

Antivirus Scan uses these warning in an attempt to scare you into believing that your computer is being attacked by a wide variety of spyware and viruses.

In order to make the detection list more convincing, this program also generates security warning pop-up messages, which announce security threats. Be aware that Antivirus Scan does not scan your computer for security issues; these processes are merely imitated.

This bogus program has no legitimate virus definition database and ‘detects’ random, harmless files as being malware. Internet criminals responsible for creating this rogue program hope that you will fall for their trickery and purchase a license for Antivirus Scan to remove security threats that do not actually exist.

If you purchase this program, you will send your money to Cyber criminals and your computer will remain infected. Use the removal guide to remove Antivirus Scan.

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.
