DefenceLab is a rogue security program that displays alarming security alerts and fake system notifications to the user in order to frighten them.  This is done to convince the user that threats and malware have been detected, so that they will purchase DefenceLab to remove these threats.  DefenceLab is not capable of detecting or removing any spyware or infection, and in fact is an infection itself.  Malware such as this may cause your PC to become slow or unstable.  Private information such as passwords and online business accounts may be accessed as well.  DefenceLab collects information about your interests in order to transmit this data to remote servers.  Additional spyware may be installed as well, putting security further at risk.
