In recent years we have been almost overwhelmed by the prevalence of viruses and worms spreading across networks. However, we have a wake-up call that viruses on removable media are still a threat. W32/Barcos.A copies itself to floppies and CD-Rs, and it also drops another type of virus not in the news recently, a Word Macro virus, W97M/Bacros.A, and carries a destructive payload. When infecting CD-Rs, it creates an AUTORUN file, so that it will get executed automatically when the disk is inserted into a default-configuration Windows PC.
W32/Barcos.A is reported to be spreading in Scandinavia.
