TheDefend is a rogue antispyware program that spreads mostly through the use of trojans which usually pretend to be flash updates, or even video codecs required to watch movies online.
Once installed, the trojan will install TheDefend onto your computer and will configure it to run automatically when Windows loads. The trojan will also create a lot of files with random name in Windows and Windows\System32 folders. All of these files are harmless, but TheDefend during the scan will label them as infections to trick you think that your computer in danger. Of course, the scan results are fake and you should ignore all that the program gives you!
What is more, the trojan that installs TheDefend will also install a variant of trojan FakeAlert. Once running, the trojan will show a screen that looks like Windows Security Center and a lot of fake spyware alerts and nag screens. An example:
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 TheDefend and remove spyware
threats from your PC.
Of course, all of these alerts are fake and like false scan results should be ignored! As you can see, TheDefend is a scam and should be removed upon detection. It designed with one purpose, to trick you into purchasing so-called “full” version of the program!
