The W32.Blaster.Worm is a worm which spreads over the network mainly on the Internet. He uses for this purpose the so-called weak spot DCOM RPC. The W32.Blaster.Worm files itself in the system directory (standard: C:\Windows\System32 or C:\Winnt\System32) under the name MSBLAST.EXE. Because of the change in the registration this file runs on every start of the computer. W32.Blaster.Worm attempts to perform a Denial of Service (DoS) on the Microsoft Windows Update Web server (windowsupdate.com) that tries to prevent the user from applying a patch on the computer against the DCOM RPC vulnerability.
