Malware Cleaner 2009 is a rogue security application that should not be trusted. It uses Trojan horse programs to infect computers, then generates fake security warnings to trick users into allowing it to perform a system scan. The scan that it performs is a complete fake and produces a list of fake infections to scare the user into the next part of its scam.

Once it has scared the user with its fake infections, it tells them to buy the full version of Malware Cleaner 2009 in order to remove the threats. However, the full version is completely useless. Instead of helping, it only causes the computer to slow down, generates pop-ups, and offers no protection whatsoever.
