Technical DetailsWhen an infected file is opened on Win98/ME system, the worm copies the file in \%WINDIR%\%SYSTEMDIR% directory, as WQK.EXE hidden file. This file has variable size and content.
Then, the virus makes a registry entry, for automatic start of WQK.EXE. By restart, the virus infects .exe files. When an infected file is opened on WinNT/2000/XP system, the worm copies the file WQK.DLL in %SYSTEMdir% and makes the registry entry:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ Windows\AppInit_DLLs=Wqk.dll

The virus has a payload, which overwrites all files with nulls.
