A virus identity (IDE) file which provides protection is

At the time of writing, Sophos has received no reports from
users affected by this worm. However, we have issued this
advisory following enquiries to our support department from
customers.

W32/Kelvir-H is an instant messaging worm for the Windows platform.
W32/Kelvir-H attempts to spread by sending a message through Windows Messenger
that encourages the recipient to download a file from a website at
members.lycos.nl/csecurity/screensaver/Screensaver.scr, and contains one of the
following lines of text:
"Damn, this is so sick!!"
"This is coooollll!!! w0w!"
"What a cock :| Damn ACCEPT!!"
"What a sick dude, lol!!"
"This guy is sooo lucky, what a chick!"
In order to be able to run automatically when Windows starts up, W32/Kelvir-H
sets the following registry entries with the path to the runing file:
HKLM\Software\Microsoft\Windows\CurrentVersion\Run\Microsoft Services
HKLM\Software\Microsoft\Windows\CurrentVersion\RunOnce\Microsoft Services
HKLM\Software\Microsoft\Windows\CurrentVersion\RunServices\Microsoft Services
HKLM\Software\Microsoft\Windows\CurrentVersion\RunServicesOnce\Microsoft
Services
HKCU\Software\Microsoft\Windows\CurrentVersion\Run\Microsoft Services
In attempt to hide itself W32/Kelvir-H sets the registry entries:
HKCU\Software\Microsoft\Windows\CurrentVersion\Policies\System\
DisableTaskMgr
dword:00000000
HKCU\Software\Microsoft\Windows\CurrentVersion\Policies\System\
DisableRegistryTools
dword:00000000
