DefenceLab is the latest in fake security tools, disguised as a legitimate antispyware application, this dubious application will only cause damage to any system it has infiltrated.

What sets DefenceLab apart from all the other rogue antispyware applications is the fact that it makes use of FakeAlert pop-up messages to direct the unsuspecting user to a Microsoft Support page (http://support.microsoft.com/kb/896861). The page is modified and links are replaced, so, instead of removing DefenceLab, the links actually trick people into downloading \"DefenceLab\".

DefenceLab may be capable of displaying the following properties:

1. Severely compromises a computer system’s security.
2. Opens illicit network connections
3. Makes use of polymorphic tactics to self-mutate
4. Disables security software
5. Modifies system files
6. Installs additional malware.
7. These risks may also collect and transmit personally identifiable information (PII) without your consent and severely degrade the performance and stability of your computer.

DefenceLab is sneaky, and may hide itself within registry files on an infected system; therefore there are a few sure ways to tell whether your system may be in jeopardy of infection.

In order to protect your system against the threat of DefenceLab, there are 4 main rules you should always adhere to:

• Rule 1:
Keep your Windows up to date. (Tip: Regularly visit Windows Update and set your PC to receive security and critical updates automatically)

• Rule 2:
Download and install a reliable anti-spyware program, one that will recognise the current form of DefenceLab, as well as other forms of spyware.

• Rule 3:
Install a firewall onto your system, and keep it turned on. A firewall is essential for complete protection for your system.

• Rule 4:
Keep the definitions in your anti-spyware up to date at all times.

One will need to remove DefenceLab from the infected computer system, as soon as it has been detected. The thing about DefenceLab, and many rogue anti-virus applications, is that fact that it is extremely difficult to delete from an infected system.

All in all though, I would recommend that one should make use of a reliable and legitimate, fully functional, up-to-date anti-spyware application, to remove DefenceLab and all its components from the infected computer system.
