Brief Description 

    

Chack.BS is a macro virus virus that infects Word 97 documents and the global template that this application uses.

Chack.BS uses the normal means of infection used by macro viruses. First of all it infects the global template and then it infects all the documents opened, closed or saved on the affected computer.

Chack.BS also disables certain Word options and increases the size of the Word documents it infects.

Visible Symptoms 

    

Chack.BS is very easy to identify, as when the user opens an infected document, it displays a message with a request:

  • If the user enters the word raquel or RAQUEL, the virus doesn't do anything.
  • If the user doesn't enter one of the words above, it infects the computer using the routine described in Means of infection.
