· 600 MB of free hard drive space (for installation purposes) · 512 MB of RAM memory 2.4. Uninstall Previous Versions If you have an older version of AVG Email Server installed, you will need to uninstall it manually before installing AVG 9.0 Email Server Edition. You must manually perform the uninstallation of the previous version, using the standard windows functionality.
For MS Exchange 2003 Server no additional service pack is needed; however, it is recommended to keep your system as up to date with the latest service packs and hotfixes as possible in order to obtain maximal available security. Service Pack for MS Exchange 2003 Server (optional): http://www.microsoft.com/exchange/evaluation/sp2/overview.mspx At the beginning of the setup, all system libraries versions will be examined.
3. AVG Installation Process To install AVG on your computer, you need to get the latest installation file. You can use the installation file from the CD that is a part of your box edition but this file might be out-of-date. Therefore we recommended getting the latest installation file online. You can download the file from the AVG website (at http://www.avg.com/download? prd=msw). During the installation process you will be asked for your license number.
3.2. License Agreement The License Agreement dialog provides the full wording of the AVG license agreement. Please read it carefully and confirm that you have read, understood and accept the agreement by checking the I have read license agreement checkbox and pressing the Accept button.

3.4. Select Installation Type The Select Installation Type dialog offers the choice of two installation options: Standard Installation and Custom Installation. For most users, it is highly recommended to keep to the Standard Installation that installs AVG in fully automatic mode with settings predefined by the program vendor. This configuration provides maximum security combined with the optimal use of resources.
Press the Next button to continue the installation process. If in the previous step you have selected the standard installation, you will be redirected directly to the Setup Summary dialog. If custom installation was selected you will continue with the Destination Folder dialog. 3.6. Custom Installation - Destination Folder The Destination folder dialog allows you to specify the location where AVG should be installed. By default, AVG will be installed to the program files folder located on drive C:.

If the default settings do not suit you, you can remove/add specific components. However, you can only select from components that are included in your purchased AVG edition.

7.2. Anti-Spam Principles Spam refers to unsolicited e-mail, mostly advertising a product or service that is mass mailed to a huge number of e-mail addresses at a time, filling recipients’ mail boxes. Spam does not refer to legitimate commercial e-mail for which consumers have given their consent. Spam is not only annoying, but also can often be a source of scams, viruses or offensive content. Anti-Spam checks all incoming e-mail messages and marks unwanted e-mails as SPAM.
· Value 90-99 - Most incoming e-mail messages will be delivered normally (without being marked as spam). The most easily identified spam will be filtered out, but a significant amount of spam may still be allowed through. · Value 80-89 - E-mail messages likely to be spam will be filtered out. Some nonspam messages may be incorrectly filtered as well. · Value 60-79 - Considered as a quite aggressive configuration. E-mail messages that are possibly spam will be filtered out.
There are the following options to choose from: · A specific e-mail client - if you use one of the listed e-mail clients (MS Outlook, Outlook Express, The Bat!, Mozilla Thunderbird), simply select the respective option · Folder with EML files - if you use any other e-mail program, you should first save the messages to a specific folder (in .eml format), or make sure that you know the location of your e-mail client message folders.
In this dialog, please select the folder with the messages you want to use for training. Press the Add folder button to locate the folder with the .eml files (saved e-mail messages). The selected folder will then be displayed in the dialog. In the Folders contain drop-down menu, set one of the two options - whether the selected folder contains wanted (HAM), or unsolicited (SPAM) messages.
Note: In case of Microsoft Office Outlook, you will be prompted to select the MS Office Outlook profile first. In the Folders contain drop-down menu, set one of the two options - whether the selected folder contains wanted (HAM), or unsolicited (SPAM) messages. Please note that you will be able to filter the messages in the next step, so the folder does not have to contain only training e-mails. A navigation tree of the selected e-mail client is already displayed in the main section of the dialog.
In this dialog, you can set filtering of the e-mail messages. If you are sure that the selected folder contains only messages you want to use for training, select the All messages (no filtering) option. If you are unsure about the messages contained in the folder, and you want the wizard to ask you about every single message (so that you can determine whether to use it for training or not), select the Ask for each message option. For more advanced filtering, select the Use filter option.
slider left or right to change the level of scanning performance ranging between Low memory / High performance modes. · Low memory - during the scanning process to identify spam, no rules will be used. Only training data will be used for identification. This mode is not recommended for common use, unless the computer hardware is really poor. · High performance - this mode will consume large amount of memory.
The RBL (Realtime Blackhole List) server is a DNS server with an extensive database of known spam senders. When this feature is switched on, all e-mail messages will be verified against the RBL server database and marked as spam if identical to any of the database entries. The RBL servers databases contain the latest up-to-the-minute spam fingerprints, to provide the very best and most accurate spam detection.

Once you have such a list of senders and/or domain names prepared, you can enter them by either of the following methods: by direct entry of each e-mail address or by importing the whole list of addresses at once.

8. AVG Settings Manager The AVG Settings Manager is a tool suitable mainly for smaller networks that allows you to copy, edit and distribute AVG configuration.
