Troj/Hackarmy-B is a backdoor Trojan for the Windows platform.
In order to run on system startup, Troj/Hackarmy-B copies itself into the Windows system folder as ZoneAlarmPr0.exe and creates the following registry entry:
HKLM\Software\Microsoft\Windows\CurrentVersion\Run\
Winsock32driver = <Windows system folder>\ZoneAlarmPr0.exe
The Trojan then awaits backdoor commands from a remote user.
