Brief Description 

    

Chack.AL is a macro virus virus that infects Microsoft Word documents in which it inserts a text and the global template that this application uses.

Chack.AL uses the usual means of infection used by macro viruses. First of all it infects the global template and then it infects all the Word files opened, created or saved on the affected computer. In these documents, it inserts a text in different colors and sizes.

Chack.AL also disables certain Word options, displays a blank form on screen and sometimes runs Windows Solitaire.

Visible Symptoms 

    

Chack.AL is very easy to recognize, as:

  • If the user of the affected computer uses Word, the virus displays a message when the program is closed.
  • It sometimes runs Windows Solitaire. Therefore this card game will activate for no apparent reason.
  • Chack.AL sometimes runs a macro that inserts a text in the active Word document. This text will appear in the document for no apparent reason:
