P97M/Attach is the first PowerPoint 97 macro virus. It was found in December 1998. It has several design flaws which make it extremely unlikely to spread.
Once detected, the F-Secure security product will automatically disinfect the suspect file by either deleting it or renaming it.
More information on scanning and removal options available in your F-Secure product can be found in the Help Center.

Attach is a direct-action infector, infecting all *.PPT files in the "C:\My Documents" folder, provided that their name doesn't start with a "~" (i.e., are not currently opened) and is not the same as the name of the presentation from which the virus is running.
In order to be infected, the presentation must contain user forms. All user forms of the presentation will be infected, with the virus inserting its code in front of the code already in the user form. (Most user forms contain at least some code already, since it doesn't make much sense to create an empty user form which does not respond to any events like button clicks, etc.).
The virus replicates only when the user terminates the form by clicking at the [x] button in the upper right corner of the form's window.
PP97M/Attach is not known to be in the wild, and is not likely to be, ever.
