Summary

This trojan erases data on a hard drive and attempts to corrupt Flash BIOS when executed. The trojan itself is a standalone Windows PE executable. It works under Win95/98 only.

To erase disk data and corrupt Flash BIOS the trojan uses the routine from 'Win95.CIH' (aka 'Chernobyl') virus. It seems that trojan code was compiled from the 'Win95.CIH' virus sources, where all infection routines were removed and only payload routine was left.
