GreatDefender

GreatDefender (Great Defender) is a malicious rogue antispyware application that creates files on your computer system, in order to trick you into believing that you have all types of threats on your computer system. GreatDefender is a clone of rogues TheDefend, GuardPcs, IGuardPc, SiteAdware, AntiTroy, AntiKeep, AntiAdd, RESpyWare, REAnti, KeepCop, SecureKeeper, LinkSafeness, AntiAid, SystemFighter, SystemVeteran, ProtectPcs and Apcprotect. Once you are scared enough it will take complete advantage of this false situation which it has created and will offer you a solution in the form of the full version which is also fake. It will ask you to pay a small fee, which it then promises will fix all your computer problems. The truth of the matter is that the only computer problem which you actually have is GreatDefender itself.

GreatDefender comes from the Winisoft family, and this “Defender” will not produce any protection to your personal system, instead only making it more vulnerable to cyber criminals and third parties’ manipulation. The program may cost a low $49.95; however, this price hides a deceitful pathway to your private data’s breaching, and if you decide to make any bank transactions for schemers’ bogus malware removal product, these crooks might be enabled to collect such private information as credit card numbers, full name, address, etc. There are many ways in which cyber criminals could use this data, but it definitely will not be used to produce malware removal services.

There is no doubt that schemers will employ every single deceitful stunt known to succeed at tricking your money out of you, and legitimate-looking rogue antispyware’s interface is just one of those cunning attributes. Fictitious interface’s computer scanner will claim to have detected tens of infections, and various security pop-up alerts will make you think that this malware has to be deleted. Note that the cunning interface and notifications has been noticed running in English, German, French and Italian languages, and below you will see fake warnings in two of the noted languages:

Spyware Alert! Your computer is infected with spyware. It could damage your critical files or expose your private data on the Internet. Click here to register your copy of GreatDefender and remove spyware threats from your PC.

Spzprogramm Warnzeichen!
Ihr Computer ist mit Spionprogramm infektioniert. Das kann Ihren Dateien und die im Internet zugänglich machen. Klicken bitte hier, um Ihre Kopie von GreatDefender zu registrieren und Ihr PC von Spyprogramm frei zu machen.

These notifications are fake, but you will not be able to remove them from your screen, until you successfully delete GreatDefender infection itself. And this might become very complicated, because any removal operations will be aggravated by blocked Internet connection, removed access to Windows Tools (Registry Editor and Task Manager), disabled Windows Security Center, and various other system paralyzing dysfunctions. What is more, you might have trouble rebooting into safe mode, and this will cause serious troubles at having GreatDefender deleted.

The best advice that can be offered is for you to remove GreatDefender immediately upon detection. You could make use of the manual removal instructions but you need to be seriously warned that you run the risk of causing even further damage to your computer if you do something incorrectly. It is strongly advised that you rather make use of a decent and up to date antispyware removal tool that is able to both detect as well as automatically delete GreatDefender for you.
