For more information of Word macro viruses, see the description of Concept.
WM/Imposter.A is a common Word macro virus, which is similar to DMV and Concept viruses.
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.
When it first infects a system, it displays a dialog box with text 'DMV'.
Imposter.A contains a comment which reads:
just to prove another point
Imposter.A only replicates.
Variant:Imposter.E(Wormy-1, PC-Format)
Origin:Greece
Unlike Imposter.A, this variant is not very similar to DMV or Concept viruses.
When the virus infects the system for a first time and the user exits Word, it displays the following message in the status bar:
WORMY-1 by NAENBGOURSG
After that Imposter.E infects every document when they are saved. It also re-infects files that have been infected already.
Virus also contains this text within its code:
by NAENBGOURSG SO.HT.AI.KS 231076-GREECE Thanks to NEURO VRD 19-4-1997 VRP A.U.A
Otherwise the virus just spreads.
