Imposter.A only replicates.
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.
