Brief Description 

    

Passbox.K is a macro virus that reaches the computer in an infected Word document with a DOC extension. Then, it infects Word’s global template (NORMAL.DOT file), and from there Passbox.K infects all the Word files generated with it.

Passbox.K disables some Word options and sometimes password-protects files. As a result, the user of the affected computer will not be able to access these files.

Visible Symptoms 

    

If the key Esc is disabled or the computer asks you for a user name and password when trying to open a Word document, Passbox.K may have infected your computer.
