Fujack.K is also known as Worm.Win32.Fujack.k, Whboy, W32.Fujacks.E.

Explanation :

Fujack.K is a virus and a network worm. It infects executable files with certain extensions by prepending its body to these files. It also infects webpages by appending an IFrame tag and a malicious URL to them. The worm actively spreads to external media, for example to USB drives or network drives. It attempts to perform a dictionary attack in order to break weak network share passwords. In addition, the worm kills processes belonging to anti-virus and security software as well as processes of the Task Manager and Registry Editor. The worm can download and run malicious files from a website.

Fujack.K was possibly created by the author of the Viking virus-worm.
