Manual Removal
As an alternative to using the removal tool, you can remove this threat manually. Here are the major steps:
Disconnect from the network if connected.
Update the virus definitions.
Run a full system scan, and delete all files that are detected as W32.Opaserv.Worm
Delete the values
ScrSvr %windir%\ScrSvr.exe
and
ScrSvrOld <original worm name>
from the registry key
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
(Windows 95/98/Me only ) Delete the line
run= c:\ScrSvr.exe
or
run= c:\tmp.ini
from the C:\Windows\Win.ini.
For details on how to do this, read the following instructions.
To disconnect from the network:
If you are on a network, or have a full time connection to the Internet such as DSL or Cable modem, you must disconnect the computer from the network and the Internet. Disable sharing before reconnecting computers to the network or to the internet. Because this worm spreads by using shared folders on networked computers, to ensure that the worm does not reinfect the computer after it has been removed, you must remove all shares, clean all computers on the network, patch all systems, and update definitions on all computers before you reconnect to the network or reenable shares.
IMPORTANT:
Do not skip this step. You must disconnect from the network before attempting to remove this worm.
For additional information on file sharing, read your Windows documentation or the document How to configure shared Windows folders for maximum network protection.
When you have finished the removal procedure, if you decide to reenable file sharing, Symantec suggests that you do not share the root of drive C. Share specific folders instead. These shares must be password-protected with a secure password. Do not use a blank password.
Also, before doing so, if you are using Windows 95/98/Me, you must download and install the Microsoft patch from
