Certain boot viruses, for example, prevent booting properly from the hard disk or seeing the hard disk at all. For additional information, go to the \support\edisk folder on the product CD. Rescue Disks ------------ For information on Rescue Disks, see the Readme.txt file in the Rescue folder. Email message headers contain "X-NAV-TimeoutProtection" ------------------------------------------------------- Norton AntiVirus (NAV) Email Protection options include a feature called Timeout Protection. This provides protection for your email client software during email transfers. If your POP3 email server sends a message with an attachment to the NAV POP3 email scanner without Timeout Protection enabled, there is a possibility you could lose the message. Timeout Protection sends "X-NAV-TimeoutProtection?:X" as a continuous header to the email client until the incoming message is complete. If you have multiple "X-NAV-TimeoutProtection?:X" entries in the header, it indicates how long it took to get the complete message from your POP3 incoming mail server. To turn off Timeout Protection, follow these steps: 1. Start Norton AntiVirus 2001. 2. Click Options. 3. Double-click Email Protection, and then click Advanced. 4. Uncheck "Protect against timeouts when scanning email." This will remove the "X-NAV-TimeoutProtection?:X" header information. 5. Restart your computer. Using the Windows ME restore feature with Norton AntiVirus ---------------------------------------------------------- Restoring your system to a previous setting using Windows Me System Restore might revert virus definition engine changes and cause mismatched virus definitions. To solve this problem run LiveUpdate to install the latest virus definitions. If you are also running older versions of Norton products --------------------------------------------------------- If you have both this new Norton product installed and any 2000 version Norton product installed on your computer, the LiveAdvisor button on the menu bar of your 2000 version Norton product will be removed. As LiveAdvisor is no longer being used for information delivery, there is no loss of functionality. As was explained in the final LiveAdvisor messages, Symantec has replaced the LiveAdvisor delivery mechanism with information on the Symantec web site (http://www.symantec.com) and product-specific newsletters (http://www.symantec.com/techsupp/bulletin/index.html). In this way we can offer information of specific interest to you as quickly as possible. Using Norton AntiVirus Email Scanning with Wingate ------------------------------------------------- Norton AntiVirus email scanner uses port 110 to check incoming email for viruses. Wingate also uses this port. To change the port Norton AntiVirus uses, change the following Windows registry key: HKEY_LOCAL_MACHINE\SOFTWARE\Symantec\Norton AntiVirus \eMail Protection\Default Port Change the value of this entry to an unused port (port 22000 is usually available). If you enter a port that is already in use, Poproxy (the Norton AntiVirus email scanner) will not start. You must also unconfigure all of your email clients and re-configure them so they will work with the new port. Even after doing this some email clients, including Netscape, will not work because they do not support ports other than 110. Using Norton AntiVirus with Pegasus Mail ---------------------------------------- When using Norton AntiVirus email Scanning with Pegasus mail using long email address, you may reach the Pegasus 55 character email address limit. To retrieve email again, disable Norton AntiVirus email protection from this account. You will need to update your server name and user name in Pegasus mail. Install freeze when using outlook express with SPA -------------------------------------------------- When installing Norton AntiVirus on a Windows 95b machine using IE4 and Outlook express with Secure Password Authentication enabled, the system may pause for a few minutes. This is due to an older version of Winsock used in this system. Updating to the latest version of Winsock from Microsoft's website will solve this problem. Automatic LiveUpdate requirements --------------------------------- Automatic LiveUpdate requires Microsoft Internet Explorer 4.0 or later and Microsoft Task Scheduler. Using Netscape with Norton AntiVirus ------------------------------------ If Norton AntiVirus is installed as a Netscape helper application, a downloaded file will be lost if Netscape is closed before the download is complete. Using Norton AntiVirus with Netscape 6.0 ---------------------------------------- Norton AntiVirus Netscape Plug-in does not support Netscape 6.0 due to the removal of helper application functionality from Navigator. Using Norton AntiVirus with Netscape 4.x ---------------------------------------- Netscape 4.x uses a feature called Smart Download. This feature is launched each time you download a zip file and it handles the download without running it through the Norton AntiVirus plugin. Virus protection is provided by Norton AntiVirus Auto-Protect when you extract files from the compressed file. 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 your disk. LiveUpdate subscriptions ------------------------ With the purchase and installation of Norton AntiVirus 2001, you automatically qualify for limited free use of LiveUpdate to receive virus definition updates. Your installed Norton AntiVirus program will notify you when your subscription is about to expire and provide information on how to extend your subscription to ensure continuing, up-to-date protection. Print versions of Norton AntiVirus Guides ----------------------------------------- Print versions of the Norton AntiVirus User Guide 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 or LiveReg ---------------------------------- Because LiveUpdate and LiveReg are shared by several Symantec products, it is not uninstalled automatically if you select Uninstall Norton AntiVirus. Do not uninstall these components if there is any other Symantec software installed on your system. To uninstall LiveUpdate or LiveReg, choose Add/Remove Programs from the Windows Control Panel and select LiveUpdate or LiveReg. Quarantining non-deletable files -------------------------------- Norton AntiVirus cannot automatically 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. 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. Scheduling scans in Windows 95 ------------------------------ Norton AntiVirus for Windows 98/ME and Windows 95 use different schedulers. The Windows 98/ME version uses the built-in Windows scheduler, while the Windows 95 version uses the Norton Program Scheduler. In Windows 95, if your computer is turned off when a scheduled task is suppose to run, Norton Program Scheduler will notify you the next time your computer is started. Win 95/98 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 the AP text message from displaying 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. 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, visit this site: http://www.eicar.org/anti_virus_test_file.htm Disable Auto-Protect temporarily before you save the file. 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." "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. 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. Updating Windows 95/98/Me video drivers for Auto-Protect ----------------------------------------------------- Some versions of Windows 95/98/Me 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. Disabling email scanning while a download is in progress -------------------------------------------------------- Norton AntiVirus does not support disabling email scanning while an email download is in progress. If you do this and if the email that you are downloading contains an infected file attachment, portions of this infected file attachment might be left in your TEMP directory (usually C:\WINDOWS\TEMP or C:\TEMP). It is recommended that you delete this file. If you should attempt to extract the infected contents of this file, Norton AntiVirus Auto-Protect will protect you from any infections. Upgrading to Windows NT or Windows 2000 --------------------------------------- Uninstall Norton AntiVirus before installing Windows NT or Windows 2000 on your computer. Reinstall Norton AntiVius after the new operating system is installed. Secure Live Registration issues with Windows 95 OSR2 ---------------------------------------------------- If you are running Windows 95 OSR2 and would like to use Secure Socket Layer (SSL) to register, upgrade Internet Explorer to at least version 4.01 SP2. You can download this upgrade from http://www.microsoft.com/windows/ie/download/ie401sp2.htm. Once you have upgraded Internet Explorer, you can register your Norton product from Help > About. Error starting email protection ------------------------------- If you see the error "Norton AntiVirus is unable to start email protection. Please ensure that TCP/IP is installed and port 110 is available," it might be because you are running a firewall program. If you are using a firewall, the firewall must be configured to allow Poproxy.exe permission to access the Internet on port 110. Using Norton AntiVirus with Netscape Previews ----------------- Norton AntiVirus does not automatically configure Netscape Previews for email protection. You can configure it manually for email protection. Email protection does not work with Eudora 5 beta ------------------------------------------------- Norton AntiVirus email protection does not work with the beta release of Eudora 5. Manual configuration does not work. ********************************************************************** END OF FILE **********************************************************************
