OpenCloud Antivirus - how to remove?

What is OpenCloud?

OpenCloud antivirus is a fake computer security scanner derived from the same family of misleading scanners as WolfRam Antivirus and Blueflare Antivirus. Like its predecessors, OpenCloud antivirus is a scam created with only one intention - to steal money from your credit card account. This rogue computer program is installed on your computer without permission and can occur while surfing misleading websites. These websites exploit various security vulnerabilities in order to install OpenCloud Antivirus on your computer.

When your PC is infected with this bogus program, your desktop will be flooded with various fake security warning pop-ups, indicating that your computer has serious errors. A fake security checkup will be initiated each time you start your computer. This scan will 'detect' a large amount of malware on your hard drive, and if you click the "Remove Threats" button in the main window of OpenCloud antivirus, you will be redirected to a website where you will be encouraged to purchase a full version of the program. You should not buy the program - it is fake security software created by Internet criminals. The program does not actually scan your computer for security threats - this process is merely imitated to scare you into believing that your computer is heavily infected. You should ignore the security scans and security warning pop-ups generated by OpenCloud antivirus and remove this fake program from your computer immediately.

The following is an example of fake alerts generated by OpenCloud Antivirus:

"Warning! The file "taskmgr.exe" is infected. Running of application is impossible. Please activate your antivirus software."

"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."

"Warning! Infection found. Unauthorized sending E-MAIL with subject "RE:" to was CANCELLED."

"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."

"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. 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."

"Warning: Infection is Detected. Windows has found spyware infection on your computer! Click here to update your Windows antivirus software."

Ignore these fake messages and remove OpenCloud Antivirus from your computer.

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:
