Windows 98 may not restart properly if anti-virus programs are running. For example, if Norton AntiVirus Auto-Protect is running, Windows 98 Setup will not restart your computer automatically during the upgrade. If your computer stops and doesn't restart when it is supposed to during the upgrade, turn the power off and then on again to restart your computer manually. Windows 98 Setup will then properly continue. Inoculation Alerts when upgrading to Microsoft Windows 98 --------------------------------------------------------- If you receive an Inoculation Alert during a virus scan after upgrading from Microsoft Windows 95 to Windows 98, choose Inoculate to respond to the alert. Do not choose Repair. In this case, the inoculation change is expected because of the Windows upgrade. If you choose Repair, you will corrupt the data on your disk. Print versions of Norton AntiVirus Guides ----------------------------------------- Print versions of the Norton AntiVirus User and Implementation Guides can be ordered through Symantec Customer Service. Uninstall Beta versions of Norton AntiVirus ------------------------------------------- If you tested a Beta version of Norton AntiVirus, uninstall the Beta before installing the release version. This removes unneeded files that would otherwise remain on your disk and prevents problems that could arise due to changed file formats. Uninstalling LiveUpdate ----------------------- Because LiveUpdate is shared among Symantec products, it is not uninstalled automatically if you select Uninstall Norton AntiVirus. To uninstall LiveUpdate, choose Add/Remove Programs from the Windows Control Panel and select LiveUpdate. Removing Norton AntiVirus from the Windows Start menu ----------------------------------------------------- If Uninstall does not remove the Norton AntiVirus program group from the Windows Start menu, you must remove it manually. To remove the program group, right-click the taskbar, select Properties, click the Start Menu Programs tab, click Remove, select Norton AntiVirus, and then click Remove. Options settings from earlier versions of Norton AntiVirus ---------------------------------------------------------- Options settings from earlier versions of Norton AntiVirus are not preserved when you install Norton AntiVirus 4.0. The new version stores options settings in a different format. Installing Norton AntiVirus and Microsoft Outlook 98 ---------------------------------------------------- If Microsoft Outlook 98 is running during Norton AntiVirus installation, the install will take a long time. Close Microsoft Outlook 98 before installing Norton AntiVirus. Novell NetWare: Installing from long filename (LFN) directories --------------------------------------------------------------- Norton AntiVirus cannot be installed from long filename (LFN) directories under Novell NetWare. Quarantining non-deletable files -------------------------------- Norton AntiVirus cannot quarantine non-deletable files (for example, files infected by the DirII virus). To manually add these types of files to the Quarantine, open the Quarantine and choose Add Item. NAVDX and Long Filenames (LFNs) ------------------------------- NAVDX, the command-line scanner used for startup scans and emergency recovery, does not properly display long filenames in a DOS box. Inoculation Change Alerts ------------------------- When responding to an inoculation change alert, you must determine if the change is legitimate (choose Inoculate to let Norton AntiVirus generate new inoculation data) or the change indicates the activity of a virus (choose Repair to let Norton AntiVirus restore the item). The following examples demonstrate legitimate changes. In these cases you should choose Inoculate to let Norton AntiVirus generate new inoculation data. * Installing or Upgrading Windows If you are running Norton AntiVirus and reinstalling or upgrading Windows, you may receive more than one inoculation change alert. Choose Inoculate, not Repair, to respond to the alert. Windows modifies boot records during the install operation and restarts your system more than once. Each time your system is restarted, these changes are properly detected by Norton AntiVirus. If you choose Repair, you are undoing some of the changes that Windows is making and, therefore, corrupting your boot records. You may not be able to start your system from its hard disk. If this occurs, start up from a floppy disk and reinstall Windows. * Partitioning Software If you use partitioning software (such as Partition Magic) or drive overlay software (such as Disk Manager and EZ drive), you may receive inoculation alerts for legitimate changes. When you set or modify partitions after Norton AntiVirus is installed, choose Inoculate, not Repair, to respond to these alerts. For example, Partition Magic may generate several legitimate inoculation alerts when setting or modifying partitions. If you choose Repair, your drive may be rendered inaccessible with little chance of recovery. AUTOEXEC.BAT and NAVDX.EXE -------------------------- During installation, an entry is placed in your AUTOEXEC.BAT file to run NAVDX for startup scans, which run before Windows starts (for example, @C:\PROGRA~1\NORTON~1\NAVDX.EXE /STARTUP). Whether or not the startup scan actually takes place is determined by your Startup tab settings in the Norton AntiVirus Options window. If, however, you remove the NAVDX line from your AUTOEXEC.BAT file, the startup scans can never occur, irrespective of your Startup tab settings. NAVDX is loaded from AUTOEXEC.BAT rather than WINSTART.BAT to ensure that it scans as early as possible during the system startup sequence. Automatic Protection and Downloading Software --------------------------------------------- If you configure Norton AntiVirus to monitor for virus-like activities, you may get unknown virus alerts when downloading program files from some online services. These alerts do not necessarily mean a file is infected with an unknown virus. The alert may be generated due to the way the file is transferred. For example, the CompuServe WinCIM program creates a file the size of the expected download when you begin a file transfer. During the transfer, the contents of this file are replaced with the data being downloaded. If you are downloading an executable program, Auto-Protect will properly notice that the file is being modified and alert you. Simply select Continue when the alert is generated to complete the download. If you frequently download programs, you can add exclusions for this behavior so that the alerts are not generated at all. For example, you could add exclusions for WinCIM for "Write to program files." Auto-Protect (NAVAPW32.EXE, NAVAP.VxD, and SYMEVNT.386) ------------------------------------------------------- Auto-Protect and Inoculation ignore disk label (volume label) changes to prevent false virus alerts. Viruses cannot use the disk label to infect your system. For the same reason, changes to the OEM ID in a boot record are not reported. By design, Auto-Protect does not report writes to a boot sector or master boot record if the new sector is identical to the one previously on the drive. For example, you may use a disk editor to write back the same data to a boot sector or master boot record. Intel platform only: Modifying Rescue Disks ------------------------------------------- Due to the number of product specific technologies used by manufacturers to configure and initialize hard disks, Norton AntiVirus cannot always create a bootable Norton Rescue Boot Disk automatically. To test your rescue disk, restart your computer from rescue disk 1, "Norton Rescue Boot Disk," and type C: to change to your hard drive. If you can access your hard drive, you can rely on the rescue disk in an emergency situation. Write-protect the disk and store it in a safe place. If, however, you cannot pass this test, you must modify the disk. In all cases, restart your computer from the newly modified rescue disk to verify proper operation. * Modifying a Norton Rescue Boot Disk for Ontrack Systems 1 Choose Shutdown from the Start menu and select "Restart the computer in MS-DOS mode." 2 After your computer restarts, insert your Ontrack Disk Manager disk in the A: drive. 3 Type A:\DM and press Enter to run the Disk Manager program. 4 Choose "Maintenance Menu" from the main window Select an Installation menu. 5 Choose "Create Ontrack Boot Diskette." 6 Choose "Make this diskette an Ontrack Boot Diskette." 7 Remove the Ontrack Disk Manager disk and insert rescue disk 1, "Norton Rescue Boot Disk," in the A: drive. Make sure the disk is not write-protected. 8 Press Enter to accept the default switches (/P-). 9 When the operation is completed, write-protect the rescue disk. 10 Restart your computer using you Norton Rescue Boot Disk and type C: to change to your hard drive to verify proper operation. * Modifying a Norton Rescue Boot Disk for embedded driver systems Because embedded driver implementations are hard drive specific, you must refer to the documentation that came with your hard disk for instructions on how to create a bootable floppy disk that gives you access to the hard disk. In some cases, you will have to contact the manufacturer's technical support department. System Shutdown and Auto-Protect -------------------------------- Auto-Protect is often configured to scan removable media devices for boot sector viruses during system shutdown. While scanning the boot sector, Auto-Protect can display a text mode message that notes it is currently scanning a boot record. Some video boards and video drivers have problems switching to text mode after the shutdown screen is displayed and cause a system lockup. Because of this, we have disabled this behavior by default. You can control whether or not the text message is displayed by merging the following Registry Entry files with your Registry: APMSGOFF.REG Prevents the AP text message from displaying APMSGON.REG Permits the AP text message to be displayed To merge a Registry Entry file with your Registry, simply double click the file from the Explorer or a My Computer window. Both files are located where Norton AntiVirus is installed. By default, this is the C:\Program Files\Norton AntiVirus folder. Note that if a virus is found, Auto-Protect will attempt to display a message irrespective of this setting. Novell Client32 for Windows 95 ------------------------------ A problem has been identified with the initial release of the Novell Client32 for Windows 95 and Auto-Protect. Under some circumstances, Auto-Protect can miss infected files when files are going between a NetWare 4.1 server and a Windows 95 client running the Novell Client32 software. Contact Novell for an upgraded version of Client32. "HIMEM.SYS is missing" Message when Restarting Your Computer ------------------------------------------------------------ On certain computers, you may see the following message when restarting your computer: HIMEM.SYS is missing. Make sure that the file is in your Windows directory. This error occurs only if you restart your computer with a warm boot (Ctrl-Alt-Del). If you turn the power off and then on again, or press the reset button, your computer starts properly. To prevent the problem from occurring, add the following line to the beginning of your AUTOEXEC.BAT file: SET DOS16M=2 After making the modification and saving your AUTOEXEC.BAT file, turn the power off and then on (or press the reset button) to restart your computer. Named Pipes and Auto-Protect ---------------------------- Auto-Protect is not compatible with the named pipes protocol, used by products such as Microsoft SQL Server 6.0. To prevent Auto-Protect scans of pipe files, select the Program Files option (the default) in the What To Scan group box on the Options/Auto-Protect tab. Do not select the All Files option. Contact technical support if you want to be notified when the program fix becomes available. Creating a test text file that looks like a virus ------------------------------------------------- To create a harmless text file that will be detected as a virus, which you can use to verify detection of viruses, logging, and alert functioning, copy the following line in to a separate file, saving it as TRIGGER.COM. This file is not a virus, but will be detected as the "EICAR Test String.70" virus. Disable Auto-Protect temporarily before you save the file. X5O!P%@AP[4\PZX54(P^)7CC)7}$EICAR-STANDARD-ANTIVIRUS-TEST-FILE!$H+H* Using Netscape with Norton AntiVirus ------------------------------------ If Norton AntiVirus is installed as a Netscape helper application, a a downloaded file will be lost if Netscape is closed before the download is complete. Changing LiveUpdate automatic schedules --------------------------------------- The first time that LiveUpdate completes a successful session, it offers to schedule future sessions automatically. If you want to modify or delete the scheduled sessions, access the Norton Program Scheduler from the Norton AntiVirus group on the Start menu or the Norton AntiVirus main window. Chips and Technologies display driver problem --------------------------------------------- A problem with the Chips and Technologies display driver, which is common in Toshiba laptops, may cause a system hang after an Auto-Protect alert is generated. Changing to a standard SVGA driver avoids the problem. NAVDX and ZIP drives -------------------- Some ZIP drives require that a disk be present when they are started. You may see an "Invalid Drive type on drive " with NAVDX, the Norton AntiVirus component that performs startup scans and scans in emergency situations, if no disk is in the ZIP drive. Insert a disk in the drive and choose "Retry." Preventing the Norton AntiVirus Startup Logo Screen from Displaying ------------------------------------------------------------------- Some users prefer not to see the startup logo screens that display when Norton AntiVirus components are loaded. They can be disabled or enabled by merging the following Registry Entry files with your Registry: LOGO_OFF.REG Disables the startup logo screen LOGO_ON.REG Enables the startup logo screen To merge a Registry Entry file with your Registry, simply double click the file from the Explorer or a My Computer window. Both files are located where Norton AntiVirus is installed. By default, this is the C:\Program Files\Norton AntiVirus folder. "IOS Failed to Initialize" error message after installation ----------------------------------------------------------- When you restart Windows 95 after installing a program or making a configuration change to your computer, you may receive one of the following error messages: * Windows initializing device IOS: Windows protection error. IOS failed to Initialize, Please restart * While initializing IOS: Windows protection error. You need to restart your computer. This is a Windows 95 problem that occurs on a very small number of system configurations. After the error message is displayed, you may not be able to start Windows 95 normally. However, you should be able to start Windows 95 in Safe mode. To correct the problem: 1 Boot Windows 95 in Safe mode or to a command prompt. 2 Do one of the following: * Edit your CONFIG.SYS and AUTOEXEC.BAT files and remove or disable any references to SMARTDRV.EXE * Rename SMARTDRV.EXE to another name (for example, SMARTDRV.EX?). For more information, visit the Microsoft Knowledge Base and review article Q157924. Network application performance issues with Auto-Protect running ---------------------------------------------------------------- Auto-Protect by default, opens files on a network drive in shared mode. This can increase the time it takes for an application to load over the network. To speedup load time of applications, you can configure Auto-Protect to open files in non-shared mode. To do this, double-click the AP_FAST.REG file located in the Norton AntiVirus folder, then restart your computer. If sharing violations occur after setting Auto-Protect to non-shared mode, reset Auto-Protect to shared mode. To do this, double-click the AP_NORM.REG file, then restart your computer. NEC platform only: CONFIG.SYS and NAVDX.EXE ------------------------------------------- During installation, Norton AntiVirus checks your system's CONFIG.SYS file for a line that loads the EMM386 memory manager. If such a line is in the file, it is remarked out so that EMM386 does not load. This is done to avoid reported problems with NAVDX on machines with 32 MB or more of RAM. If your system has less than 32 MB, you can edit CONFIG.SYS to remove the remark that Norton AntiVirus adds so that EMM386 loads as before. If you do this, you must remove any switches and parameters to EMM386, and replace them with the /DPMI switch. For example, you should change device=a:\windows\emm386.exe noems ram to device=a:\windows\emm386.exe /DPMI NAVDX will not run if you load EMM386 without the /DPMI switch. Scanning Magneto-Optical (MO) drives larger than 640 MB ------------------------------------------------------- Norton AntiVirus does not properly scan boot records on magneto- optical (MO) drives larger than 640 MB. To disable boot record scans of MO drives larger than 640 MB: * Start Norton AntiVirus, click Options, click the Scanner tab, and then uncheck Boot Records in the What To Scan group. Updating Windows 95/98 video drivers for Auto-Protect ----------------------------------------------------- Some versions of Windows 95/98 video drivers cause display corruption or an apparent system lock up when an Auto_protect alert is generated. To correct the problem, upgrade to the latest version of the video driver. Mijenix ZipMagic and Norton AntiVirus installation -------------------------------------------------- Norton AntiVirus should be installed before ZipMagic is installed. If ZipMagic is installed first, you must change a ZipMagic option setting for proper operation. To configure an already installed ZipMagic: * Access ZipMagic options and set up Norton AntiVirus as a program that recognizes ZipMagic archives as files, not as folders. For more information, consult your ZipMagic documentation. ********************************************************************** END OF FILE **********************************************************************
