OpenCloud Antivirus

Despite the continued efforts of the online security industry to educate its consumers about the dangers of rogue security tools, many PC owners are still falling victims to rogue security applications like OpenCloud Antivirus. This rogue in particular emanates from the same vindictive family of rogues as Wolfram Antivirus. OpenCloud Antivirus is classified by all major security companies are rogueware because it manipulates users into thinking their systems are being attacked and that it has the ability to protect their PCs, which it doesn’t. OpenCloud Antivirus manages to achieve this by emulating the workings of a real antivirus application. Despite all the tactics OpenCloud Antivirus will employ to convince its victims of its legitimacy, it does not have the ability to identify or remove any type of threat from the system, as it is a threat in itself.

OpenCloud Antivirus makes use of numerous established forms of infection. These may range from using browser hijacking websites which employ drive-by downloads, to using infected online ads. Other forms of infection incorporated by OpenCloud Antivirus as part of its online marketing campaign include bundled third party downloads and fake online malware scanners.

The user will remain unaware of OpenCloud Antivirus’ presence until the rogue starts its attack against the system. This will usually happen by OpenCloud Antivirus initiating a fake security scan of the system, which will then inform the user that his system is being attacked by various threats and viruses. This is indeed fake, and is only the start of OpenCloud Antivirus’ attack against the system.

The user will find after the fake scan completes that his system is being overrun by incessant fake security alerts. These fake security messages further serve to annoy and panic the user into thinking his system is being attacked, and that he needs to pay for OpenCloud Antivirus’ bogus software. Some of the more popular fake alerts to be on the lookout for include the following:

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

This is done to not only annoy and panic the user even more, but also to prevent the PC owner from executing an application which may be able to identify and remove OpenCloud Antivirus from the system. Each time the user attempts to launch an application he will be presented with the following fake alert:

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

It will also cause severely poor system performance and increased erratic system behavior, as well as hide certain system folder contents from the PC owner. To avoid this, and disable all other annoying symptoms enter the following activation key:


This key will not remove OpenCloud Antivirus from the system, but it will make its removal easier by stopping all the irritating symptoms from hindering you.

The only way you will be able to regain control of your PC will be to erase OpenCloud Antivirus for good. This can safest and easiest be achieved by making use of a genuine and powerful security tool which will offer adequate protection against similar attacks in future.
