Pokud jde o poΦφtaΦovou sφ¥ LAN, je nutnΘ VèECHNY poΦφtaΦe FYZICKY odpojit od sφt∞ a provΘst jejich dezinfekci. Jakmile jsou VèECHNY PC v po°ßdku, pak teprve celou LAN znovu "nahodit". P°φmo v prost°edφ Windows spus¥te jedno·Φelov² antivirus FIXKLEZ.COM a odstra≥te pomocφ n∞j virus Win32/Klez.H i vypuÜt∞n² virus Win32/ElKern.
