WEBsweeper installation


Preparing the WEBsweeper host

Before installation ensure that the WEBsweeper host is configured with:

Pre-installation checklist

Before installation you should:

If you are using DLL based anti-virus tools these are installed after the MIMEsweeper installation. For more details see page 3-21.

Installing WEBsweeper

After you have determined the configuration required for your network and prepared your network for WEBsweeper deployment, you can run the setup program to install WEBsweeper on the host machine.

WEBsweeper should be installed by a user with write access to the Windows NT registry (such as a user in the Administrator's group).

Before starting the installation you should ensure that:

There are several evaluation copies of anti-virus tools on the installation CD-ROM. If you wish to use any of the command line anti-virus tools you should install them separately, before proceeding with the setup program.

The release notes for MIMEsweeper may provide additional information that is required for the installation to be successful. You should read these before starting the installation.

Stopping the WEBsweeper service

If you are performing an upgrade you must shutdown the WEBsweeper service before starting the installation, to prevent file access conflicts.2

Remember to start the service again, after the upgrade is complete. See page 3-22 for details.

1. Double-click on the Services icon, found in the Control Panel.

A Services dialog box is displayed showing a list of services. Select the WEBsweeper entry and click on the Stop button.1

2. Click on the Close button to exit the Services dialog box.

Alternatively, enter the following command at the command prompt:

net stop WEBsweeper

Starting the installation

One of the files on the installation CD-ROM is called SETUP.EXE. Run this program to start the installation.

It is strongly recommended that you exit all Windows programs before running the setup program.

To proceed with the installation, follow the dialog boxes in the InstallShield setup program.

The first dialog box you will encounter is the Welcome dialog box, as shown below.

Click on the Next> button to proceed with the installation.

At this point, if an existing MIMEsweeper installation is detected that is of a version prior to version 3.0, you are informed and asked if the setup program should reorganise it before proceeding. If a version 3.0 installation is detected this reorginisation will involve the quarantine areas only.

Click on the Yes button to continue.

If you are performing an upgrade it will happen automatically. You will not be presented with any further options. During the upgrade, all your existing configuration files will be copied into the directory CONFIG\CFGBAK.

If you are not performing an upgrade you are presented with a series of dialog boxes like the one shown below, offering configuration options for MIMEsweeper.

Work your way through each of the dialog boxes, typing in or selecting information from each one, as required.

Selecting the product components

The Product Components dialog box, shown on the previous page, allows you to select the MIMEsweeper modules and components you wish to install.

For a WEBsweeper installation, check the WEBsweeper box.

The default directory for the installation is C:\MSW, as indicated in the Destination Directory area.

If you wish to change the default directory, click on the Browse... button and select a new directory from the Choose Directory dialog box.

Select the directory path by double-clicking on the folder icons that are displayed in the Directories: area. The selected directory path is shown in the Path: field.

If the directory is located on a different drive, change the entry in the Drives: field, by clicking on the down arrow to the right of the field and selecting from the displayed list.

Specifying the SNMP details

WEBsweeper is capable of generating SNMP traps at startup and shutdown. If SNMP traps are required you can enable them using this dialog box.

Check the SNMP Traps box and type in the Community and Target Address information, as follows:

SNMP traps can also be generated during disposal, see page 7-37 for details.

Specifying the anti-virus tools locations

If you intend to use command line anti-virus tools with MIMEsweeper, the next dialog box prompts you to check the box of each one you will be using.

There are several evaluation copies of command line anti-virus tools provided on the installation CD-ROM. These are not automatically installed by the setup software.

A dialog box is displayed for each anti-virus tool selected, prompting you to provide the location where each has been installed. Some anti-virus tools will also prompt for the version being used (Windows NT or MS DOS). Ensure you have all of this information readily available.

Click on the Browse... button to change the directory shown, using the Choose Directory dialog box. This dialog box is shown on page 3-17.

If you are using DLL based validators these should be installed after the MIMEsweeper installation. For more details see page 3-21.

Starting the file transfer

At this point, setup has enough information to start the file transfer operation. Your chosen options are displayed for a final accuracy check.

Check the information displayed and ensure it is correct. If any of the information is wrong, click on the <Back button to locate and change it, otherwise click on the Next> button to proceed.

The file transfer operation now takes place and the new MIMEsweeper installation is copied from the CD-ROM. A program group is created for all the MIMEsweeper components.

See page 5-4 for details on how to access the program group.

Installation of MIMEsweeper is now complete and a default configuration is in place.

Setting the licence key

You can enter your licence key at this point, by ensuring that the Set MIMEsweeper licence key box is checked before clicking on the Finish button.

You should have the licence key readily available when you run the set licence application.

Alternatively, you can enter the licence at a later time by running the Licence program. See page 4-1 for details.

Finally, click on the Finish button to exit the InstallShield setup program.

Some files may not be updated if they were being used by other programs on the system at the time of the installation. These files will be updated the next time you start your system.

Installing the DLL based anti-virus tools

Installation of the DLL based anti-virus tools occurs after the MIMEsweeper installation is complete.

These anti-virus tools can be found on the MIMEsweeper CD and come with their own instructions for installation.

Starting the WEBsweeper service

After installing WEBsweeper you must either reboot the machine or start the WEBsweeper service manually3 via the Services dialog box, accessed as explained on page 3-14.

1. Select the WEBsweeper entry from the list of services and click on the Start button.1

The Status value tells you that the service is currently Started.

2. Click on the Close button to exit the Services dialog box.

Alternatively, enter the following command at the command prompt:

net start WEBsweeper

(For MAILsweeper, use net start MAILsweeper).

See page 6-4 for more details on starting and stopping the MIMEsweeper services.

Securing the WEBsweeper machine

It is important to secure the WEBsweeper machine so that:

Securing the WEBsweeper machine can be achieved via the Network dialog box. Access this dialog box by double- clicking on the Network icon, found in the Control Panel.

First, it is necessary to disable forwarding of IP, to stop the WEBsweeper machine acting as a router. This is achieved using the following steps.

1. Click on the Protocol tab of the Network dialog box and select the TCP/IP entry from the Network Protocols area.

2. Click on the Properties button, to display a Microsoft TCP/IP Properties dialog box. Click on the Routing tab of this dialog box.

3. Ensure that the Enable IP Forwarding check box is disabled. (A tick in this check box indicates that it is enabled.)
4. Click on the Apply button to apply the changes.
5. Click on the OK button to exit the dialog box.

Next, it is necessary to disable the WINS client (TCP/IP) binding to the Server service. This disables remote access to shared resources over TCP/IP. Details on how to do this are shown on the next page.

Care must be taken when disabling the WINS binding as this may effect other network operations, such as logging into NT domains when the only network protocol used is TCP/IP.

To disable the WINS client (TCP/IP) binding:

1. Click on the Bindings tab of the Network dialog box.

2. Ensure that all services is displayed in the Show bindings for field. (Change the entry in this field by clicking on the down arrow to the right of the field and selecting from the displayed list).
3. Expand the Server entry, by clicking on the + symbol, then select the WINS Client(TCP/IP) entry.
4. Click on the Disable button. A red warning symbol to the left of the WINS Client(TCP/IP) entry indicates that it is disabled (as shown on the screen above).
5. Click on the OK button.
