Understanding iDAT Technology dat-4056.zip dat-4056.tar DELTA.INI README.TXT Best practices The following sections outline some suggestions for how to employ iDAT downloads in your updating strategy. Three-stage updating If you need to roll out new virus definitions to multiple workstations on your network, McAfee recommends a three-stage update strategy that will save you external network bandwidth, minimize your security risks, and give you more control over your internal updating strategy: 1. If the .DAT files installed on your network computers are very old, use a web browser or FTP client software to download a full .DAT file update or the SuperDAT utility to a central server on your network, then configure the AutoUpdate copies on your network computers to download and install the complete .DAT set and the current scan engine. This brings your network to a workable baseline state. You can then download and install iDAT files to keep current. 2. From the baseline state, use a web browser or FTP client software each week to download new .UPD files directly from the McAfee FTP site to a central server on your network. If you start from the baseline state described in Step 1, you can simply download the most recent .UPD file posted on the McAfee FTP site. If you have not updated in a couple of weeks, open the DELTA.INI file online, and look at the entries in the Multiple Patch and the Incremental Resolver tables to see which .UPD files you must download to update the .DAT files installed on your network, then download each of the files you need, including the DELTA.INI file. 3. Install all of the .UPD files and the DELTA.INI file you downloaded to a central server on your network, then configure the AutoUpdate copies on your network computers to download and install the iDAT set. Do not mark these files read-only, as this could cause the target computer to report an error when it tries to delete old files later. 322 McAfee VirusScan Anti-Virus Software
