Brief Description 

    

Chack.K is a macro virus whose effects are more annoying than damaging. One of the effects of this virus is that it displays an image of the virus authors.

Like most macro viruses, Chack.K reaches computers in an infected Word document with a DOC extension. This document infects Word’s global template (NORMAL.DOT file), spreading its infection to all Word files generated with it.

Visible Symptoms 

    

Chack.K displays a distorted image of the virus creators:

  • On Fridays, when the user of the affected computer selects the Exit option in the File Menu in an infected document.
  • Any time the user selects the option About Microsoft Word in the Help (?) menu.
