Manually Uninstalling the Client
Installing the OfficeScan Client
Perform manual uninstallation only if you encounter problems uninstalling the client
from the Web console or after running the uninstallation program.
To perform manual uninstallation:
1. Log on to the client computer using an account with Administrator privileges.
2. Right-click the OfficeScan client icon on the system tray and select Unload
OfficeScan. If prompted for a password, specify the unload password then click
OK.
Note: Disable the password on computers where the client will be unloaded. For
details, see Client Privileges and Other Settings on page 9-5.
3. If the unload password was not specified, stop the following services from
Microsoft Management Console:
• OfficeScan NT Listener
• OfficeScan NT Firewall
• OfficeScanNT RealTime Scan
• OfficeScan NT Proxy Service
• Trend Micro Unauthorized Change Prevention Service (if the computer runs
an x86 type platform)
4. Click Start > Programs, right-click Trend Micro OfficeScan Client, and click
Delete.
5. Open Registry Editor (regedit.exe).
WARNING! The next steps require you to delete registry keys. Making incorrect
changes to the registry can cause serious system problems. Always
make a backup copy before making any registry changes. For more
information, refer to the Registry Editor Help.
