CAUTION

Restoring SYMEVNT
You can restore SYMEVNT to your Windows 9x system by downloading and executing the self-installing file SEVINST.EXE. This file is available from the following sources:
Web page:

FTP site:
ftp://ftp.symantec.com/public/englis...nt/sevinst.exe
Windows NT
It is possible to manually uninstall SYMEVNT from a Windows NT workstation. However, there are few, if any, situations where this should be necessary and, once done, you cannot reinstall SYMEVNT using the SEVINST.EXE file. You have to reinstall one of Symantec's applications that use SYMEVNT.
