Technical Solution




You installed Symantec Client Security 3.0 on Windows 2000, and you updated your virus definitions to May 18, 2005, Revision 8. After you restart the computer, you see a Dr. Watson error message for Rtvscan.exe or Doscan.exe. The problem happens each time that a Quick Scan runs.


Symantec Client Security 3.0.1. For information about how to obtain the latest build of Symantec Client Security, read Obtaining an upgrade or update for Symantec AntiVirus Corporate Edition or Symantec Client Security.

If you cannot install Symantec Client Security 3.0.1, use one of the following workarounds.

You can prevent the creation of the startup Quick Scan on new Symantec AntiVirus clients by importing a registry file. Follow the directions that apply to your situation.

To remove the startup Quick Scan on Symantec AntiVirus clients
Stop any scans that are currently running, and then download and import the RemoveStartScan.reg file

To prevent the creation of the startup Quick Scan before installing clients
Before installing or migrating managed clients, download and import the PreventStartScan.reg file to each client.

  • Using the RemoveStartScan.reg file on a Symantec AntiVirus client removes all user-created scans. Users must re-create any scans they created after importing the registry file.
  • Both of these files only work for the currently logged in user. On computers with more than one user, each user must log on and import the file(s).

Technical Information
The DoScan.exe process is part of the default startup Quick Scan that runs after a user logs on. You can disable the startup Quick Scan in Symantec AntiVirus 10.0.1 or later.
