Systems Affected:

W32.Golsys.8020 is a multi-threaded Win32 virus. When executed, it creates the file %system%\Sysl0gon.exe. The virus will also attempt to infect all executable files that it can find, both on the local hard drive and on mapped drives.

NOTE: %system% is a variable. The virus locates the System folder. By default this is C:\Windows\System (Windows 95/98/Me), C:\Winnt\System32 (Windows NT/2000), or C:\Windows\System32 (Windows XP). The worm copies itself to that location.

Definitions dated prior to August 2, 2002 detect this virus as BloodHound.W32.1.
