Removal

Based on the settings of your F-Secure security product, it will either move the file to the quarantine where it cannot spread or cause harm, or remove it.

A False Positive is when a file is incorrectly detected as harmful, usually because its code or behavior resembles known harmful programs. A False Positive will usually be fixed in a subsequent database update without any action needed on your part. If you wish, you may also:

  • Check for the latest database updates

    First check if your F-Secure security program is using the latest updates, then try scanning the file again.

  • Submit a sample

    After checking, if you still believe the file is incorrectly detected, you can submit a sample of it for re-analysis.

    Note: If the file was moved to quarantine, you need to collect the file from quarantine before you can submit it.

  • Exclude a file from further scanning

    If you are certain that the file is safe and want to continue using it, you can exclude it from further scanning by the F-Secure security product.

    Note: You need administrative rights to change the settings.

Technical Details

WordMacro/NPad consists of a single AutoOpen macro; this makes it language independent, ie. this macro virus is able to infect localized versions of Word as well as the english Word. The AutoOpen macro is encrypted and cannot be viewed from Tools/Macro menu.

NPad has apparently been written in Indonesia: it contains these texts:

D0EUNPAD94, v.2.21, (c) Maret 1996, Bandung, Indonesia
 Macro MsWord virus, multiplatform, multi versi

NPad adds an entry to WIN.INI/Registry under Windows and uses it as generation counter. When the virus has replicated 23 times, it scrolls the above 'D0EUNPAD94' text on the status row of Word and zeroes the counter.

NPad is one of the most common Word macro viruses.

NPad might have been written by the same author as Bandung virus.
