What is OpenCloud Security?

OpenCloud Security is a fake antivirus program similar to WolfRam Antivirus, OpenCloud Antivirus, and others. Like previous versions, this bogus program imitates the running of computer security scans and then displays fake results. Do not be impressed by the professional appearance of OpenCloud Security - it is completely useless. This bogus scanner was created by Internet criminals to steal money from your credit card account and the fake software is designed to scare you into believing that your computer is highly infected with malware.  It then coerces you into paying for a non existent full version. If you click the "Remove Threats" button in the main window of OpenCloud Security, you are directed to a website where you will be encouraged to enter your banking information and purchase a full version of this fake scanner. You should not buy OpenCloud Security, as this program is proliferated through rogue websites that exploit various security vulnerabilities in order to install fake computer security scanners on your computer. The features that OpenCloud Security offers to protect your PC are fake, and the creators of this bogus program hope that you will fall for their scam and purchase a non existent full version. You should remove this fake computer security scanner from your PC immediately.

Other tools known to remove Opencloud Security:


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:

By paying for a license key of a fake antivirus program users would send their money and banking information to cyber criminals.
