W32/Netsky-E is a worm which spreads by emailing itself to addresses found within files located on drives C: to Z:.
The email subject line, message text and attachment filename are randomly chosen from internal lists.
The name of the attached file is chosen from:
"associal", "msg", "yours", "doc", "wife", "talk", "message", "response",
"creditcard", "description", "details", "attachment", "pic", "me", "trash",
"card", "stuff", "poster", "posting", "portmoney", "textfile", "moonlight",
"concert", "sexy", "information", "news", "note", "number_phone", "bill",
"mydate", "swimmingpool", "class_photos", "product", "old_photos", "topseller",

The attachment extension will be ZIP, COM, EXE, PIF, SCR, BAT or CMD and may be preceded by an extension of TXT, RTF, DOC, HTM, JPG or GIF.
When first run the worm copies itself to the Windows folder as winlogon.exe and creates the following registry entry, so that winlogon.exe is run automatically each time Windows is started:
HKLM\Software\Microsoft\Windows\CurrentVersion\Run\ICQ Net
=<Windows folder>\winlogon.exe -stealth
W32/Netsky-E attempts to delete the following registry entries if they exist:
HKLM\Software\Microsoft\Windows\CurrentVersion\Run\Taskmon
HKLM\Software\Microsoft\Windows\CurrentVersion\Run\Explorer
HKCU\Software\Microsoft\Windows\CurrentVersion\Run\Explorer
HKLM\Software\Microsoft\Windows\CurrentVersion\Run\KasperskyAv
HKCU\Software\Microsoft\Windows\CurrentVersion\Run\KasperskyAv
HKLM\Software\Microsoft\Windows\CurrentVersion\Run\system.
HKLM\Software\Microsoft\Windows\CurrentVersion\RunServices\system.
HKLM\Software\Microsoft\Windows\CurrentVersion\Run\service
HKLM\Software\Microsoft\Windows\CurrentVersion\Run\Sentry
HKLM\Software\Microsoft\Windows\CurrentVersion\Run\msgsrv32
HKLM\Software\Microsoft\Windows\CurrentVersion\Run\DELETE ME
HKCU\Software\Microsoft\Windows\CurrentVersion\Run\D3dupdate.exe
HKCU\Software\Microsoft\Windows\CurrentVersion\Run\au.exe
HKCU\Software\Microsoft\Windows\CurrentVersion\Run\OLE

HKLM\System\CurrentControlSet\Services\WksPatch
HKCR\CLSID\(E6FB5E20-DE35-11CF-9C87-00AA005127ED)\InProcServer32
