Brief Description 

    

Class.B is a Word Macro virus that reaches computers in an infected Word 97 document, with a DOC extension. Then, it infects the Word template (NORMAL.DOT file) and spreads to all the Word documents generated with it.

The effects of Class.B are more irritating than dangerous:

  • It displays the text I Think is a big stupid jerk! VicodinES Loves You / ClassPoppy, on the 14th of any month between June and December .
  • It prevents macros from being managed in Word 97 documents.

Class.B can reach computers in an infected Word document through different means of transmission.

Visible Symptoms 

    

Class.B does not show any symptoms that can alert the user that it has reached the system.

However, once the virus has infected the computer, it displays a series of very noticeable symptoms:

  • It displays the text IThink <> is a big stupid jerk! VicodinES Loves You / ClassPoppy , on the 14th of any month between June and December.
  • It disables the Macro option in the Tools menu, in the Word 97 main window.
