It is a harmless memory resident parasitic Windows virus. The virus code is partly encrypted with silly XOR loop. It installs itself into Windows memory as VxD driver, hooks IFS API and writes itself to the end of PE EXE files that are executed or opened. While infecting the virus creates a new section at the end of the file and writes its code to there.
The virus does not manifest itself in any way. It contains the text strings:
PowerFul 32 v1.1 (c) DK and -"/5
