1. What is WinXDefender?

It's rogue computer security software, tending to mislead PC user by generating fictitious computer infection alerts. This program is equipped with free scan option, but the results are false and exaggerated in order to show user that the system is infected and he is prompted to buy commercial program version to activate spyware removal function. WinXDefender is downloaded and installed by a trojan, which is closely connected with corrupt video codecs. WinXDefender removal using Add/Remove Programs tool can be useless because of a trojan which is able to renew infection over and over again.
