Ethan.O4 is a macro virus that reaches computers in an infected Word 97 document, with a DOC extension. This document then infects the global template (NORMAL.DOT file) and spreads its infection to all the Word documents generated with it.
Ethan.O4 does not cause any damage in the infected computer, as its main aims are to spread and modify the properties of the Word documents it infects.
Note: The 'O' that appears before the 4 is not the number zero but the letter O.
Ethan.O4 is difficult to recognize, as it does not display any messages or warnings that indicate that it has infected a computer.
