Please read the instructions for removing W32/Sasser-E.
More Information
W32/Sasser-E is a network worm which spreads by exploiting the Microsoft LSASS vulnerability.
For further information on this vulnerability see Microsoft Security Bulletin MS04-011.
When first run W32/Sasser-E copies itself to the Windows folder with the filename lsasss.exe and creates the following registry entry so the worm is run automatically each time Windows is started:
HKLM\Software\Microsoft\Windows\CurrentVersion\Run\
LSASS SVR = lsasss.exe
W32/Sasser-E attempts to connect out on port TCP/1022 and TCP/445. An FTP script is then downloaded and executed which connects back on port TCP/1023 to download a copy of the worm via FTP.
W32/Sasser-E displays a message box two hours after execution,
encouraging users to apply the Microsoft security patch.
