Installing VirusScan Software Using the Emergency Disk Creation utility If you choose to create an Emergency Disk during installation, Setup will start the Emergency Disk wizard in the middle of the VirusScan software installation, then will return to the Setup sequence when it finishes. To learn how to create an Emergency Disk, begin with Step 1 on page 50. You can also start the Emergency Disk wizard at any point after you install VirusScan software. Š NOTE: Network Associates strongly recommends that you create an Emergency Disk during installation, but that you do so after VirusScan software has scanned your system memory for viruses. If VirusScan software detects a virus on your system, do not create an Emergency Disk on the infected computer. The Emergency Disk you create includes BOOTSCAN.EXE, a specialized, small-footprint command-line scanner that can scan your hard disk boot sectors and Master Boot Record (MBR). BOOTSCAN.EXE works with a specialized set of .DAT files that focus on ferreting out boot-sector viruses. If you have already installed VirusScan software with default Setup options, you can find these .DAT files in this location on your hard disk: C:\Program Files\Common Files\Network Associates\VirusScan Engine\4.0.xx The special .DAT files have these names: • EMCLEAN.DAT • EMNAMES.DAT • EMSCAN.DAT McAfee periodically updates these .DAT files to detect new boot-sector viruses. You can download updated Emergency .DAT files from this location: http://www.nai.com/asp_set/anti_virus/avert/tools.asp Š NOTE: McAfee recommends that you download new Emergency .DAT files directly to a newly formatted floppy disk in order to reduce the risk of infection. Because the wizard renames the files and prepares them for use when it creates your floppy disk, you may not simply copy them directly to an Emergency Disk that you create yourself. Use the creation wizard to prepare your Emergency Disk. User's Guide 49
