This is a virus detection. Viruses are programs that self-replicate recursively, meaning that infected systems spread the virus to other systems, which then propagate the virus further. While many viruses contain a destructive payload, it's quite common for viruses to do nothing more than spread from one system to another.

Virus Characteristics

The WM/Nottice.A virus was first listed as "In The Wild" on The WildList in July 1998. The W97M/Nottice.A virus was first listed as "In The Wild" on The WildList in April 1999. W97M/Nottice.A is simply an upconversion of WM/Nottice.A.

WM/- & W97M/Nottice.A infect Word 95 & Word 97 (respectively) documents as they are opened. This virus consists of 2 macros named WININIT and AUTOOPEN. In addition, WM/- & W97M/Nottice.A infect Word's NORMAL.DOT file. This virus does not disable Word's macro virus protection.

If the date is December 13, WM/- & W97M/Nottice.A calls the WININIT module, which opens a full screen document and displays in bolded 60 point Imprint MT Shadow font the following message:


This is followed by a slight modification: the "N" in NOTTICE is redrawn to the screen, but in red and in 48 point font.
