What is Guard Online?

Guard Online is a fake computer scanner. This bogus program is derived from the same family of misleading applications as AV Guard Online, OpenCloud Security, OpenCloud Antivirus, and many others. Like previous versions, Guard Online attempts to trick computer users into purchasing a non existent full version to remove fake computer threats. Internet criminals employ various devious methods to propagate bogus scanners such as Guard Online, often using misleading websites to exploit security vulnerabilities in users' computers, in order to install fake computer software.

Guard Online rogue program

When your PC is infected with Guard Online, various security warning messages are displayed on your desktop. Furthermore, Guard Online starts automatically each time you boot your operating system, and once the rogue scanner initializes, it mimics the scanning of your computer for security threats. The fake scan reports the 'detection' of various spyware, malware, and other threats on your computer. If you click 'Remove threats' in the main window of Guard Online, you are redirected to a website where you will be asked to purchase a license for this program in order to remove the supposed security issues. Do not buy Guard Online - it is a scam. If you have already bought the license for Guard Online, contact your credit card company and dispute the charges, explaining that you have been tricked into purchasing a fake computer security program. This program merely imitates the functions of legitimate security programs, and therefore, you should remove it from your PC as soon as possible.

The following fake warning messages will be displayed on a computer infected with Guard Online:

"Windows Security Alert. To help protect your computer, Windows Firewall has blocked some features of this program. Do you want to keep blocking this program? Name: Zeus Trojan Publisher: Unauthorized."

"Security Warning. There are critical system files on your computer that were modified by malicious software. It may cause permanent data loss. Click here to remove malicious software."

"Security Warning. Malicious programs that may steal your private information and prevent your system from working properly are detected on your computer. Click here to clean your PC immediately.

"Security Warning. Your computer continues to be infected with harmful viruses. In order to prevent permanent loss of your information and credit card data theft, please activate your antivirus software. Click here to enable protection."

These security pop-ups are fake. If your computer is infected with Guard Online, you should remove it immediately.

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.
