The Setup program will create a folder called C:\temp (assuming you installed PortalProtect to the C drive). This folder contains temporary files of the installation and removal process.
After installing PortalProtect, you must set some options in the Windows SharePoint Services Central Administration Web page to engage all the features of PortalProtect. Trend Micro recommends enabling PortalProtect immediately following your installation.
Open the SharePoint Services Central Administration Web page:
Start > Programs > Administrative Tools > SharePoint Central Administration > Operations > Security Configuration > Antivirus
Select the following:
Scan documents on upload
Scan documents on download
Attempt to clean infected documents
Make sure the Windows SharePoint Services Administration service is running, which regularly checks for PortalProtect status updates for virus scanning and virus signature. You can check the service status from, Start > Programs > Administrative Tools > Services.
