Sophos Anti-Virus for Windows 95/98/Me release notes ---------------------------------------------------- Contents -------- Withdrawal of support New in this version Known problems Compatibility issues Additional information Information from previous versions Technical support Copyright Withdrawal of support --------------------- The following will no longer be supported after 31 December 2008: * Sophos Anti-Virus for Windows Me * Updating a standalone installation of Sophos Anti-Virus for Windows 95/98 * Updating Sophos Anti-Virus for Windows 95/98 from Sophos You will still be able to install and update Sophos Anti-Virus for Windows 95/98 from a central installation directory after this date. New in this version ------------------- * The threat detection engine and threat data have been updated. Known problems -------------- * Automatic downgrading from this version of Sophos Anti-Virus to earlier versions of Sophos Anti-Virus for Windows 95/98/Me is not supported. To downgrade, you are advised to manually uninstall Sophos Anti-Virus, Sophos AutoUpdate and Sophos Remote Management System, and then install the earlier version. * If you try to manually install Sophos Anti-Virus on a Windows 95 computer, the setup program might fail with the error message "This setup program cannot continue as WinSock2 (ws2_32.dll) does not exist." You must download and install the Windows Socket 2 Update on the computer from the following web address: http://download.microsoft.com/download/0/e/0/0e05231b-6bd1-4def-a216- c656fbd22b4e/W95ws2setup.exe Then re-install Sophos Anti-Virus. Compatibility issues -------------------- * Bay Networks (Performance Technologies) Instant Internet A conflict between the version of the WinSock client installed by the Instant Internet application and the Sophos SMTP.SMM module can lead to the Sophos Anti-Virus service not starting or stopping correctly. As a work-around, add the following value to the registry. (Microsoft has issued the following warning with respect to the Registry Editor: "Using Registry Editor incorrectly can cause serious, system-wide problems that may require you to reinstall Windows 95/98/Me to correct them. Microsoft cannot guarantee that any problems resulting from the use of Registry Editor can be solved. Use this tool at your own risk.") Key: HKEY_LOCAL_MACHINE\Software\Sophos\Sweep95\SMMS\SMTP\ Value Name: No Startup Check Type: REG_DWORD Data: 0x1 This work-around will prevent the SMTP module checking for the appropriate network transport protocols during startup. * Windows 95 and USB support On Windows 95 (OSR2) machines where the "USB (Universal Serial Bus) supplement" has been installed, the on-access scanner may hang on startup displaying the message "Preparing to sweep". The problem is caused by an obsolete version of the USB supplement. Customers encountering this problem are advised to remove the USB supplement using the "Add/Remove programs" icon in the control panel. When USB support is required, the latest version of the USB supplement should then be installed. * Borland C++ and Novell IntraNetWare client There is a problem when using Borland C++ 4.51 and the Novell IntraNetWare client version 3.10 together with on-access scanning. When building large projects (20+ source files), files are left locked open and cannot be deleted. This problem does not occur when using version 3.02 of the Novell IntraNetWare client. * Windows 95 Program Manager It is possible to configure Windows 95 to use a different shell instead of the normal Explorer. Windows 95 includes a version of the Windows 3.1x Program Manager which can be used as a shell. Sophos recommends against using Program Manager as a shell on a computer which runs on-access scanning. * Hewlett Packard scanners and OCR software If you experience problems such as system lock-ups or fatal exception errors when using OCR software to acquire text directly from a Hewlett Packard scanner while on-access scanning is active, you should put the following line in INTERCHK.CFG: Exclude=HPSCAN This prevents the on-access scanner from attempting to open a device name that is associated with the scanner, and that causes fatal errors if it is opened other than by the application. * Eudora When Eudora is configured by a command line option to use a network drive for its files, the on-access scanner causes it to be very slow. This is caused by the scanner's file type detection trying to identify the kind of file being accessed. The main "culprit" file is eudora.ini. You can improve performance by adding: Exclude=eudora.ini to INTERCHK.CFG. * Mijenix Corporation's ZIPMagic The on-access scanner requires the use of the DriverIoChecking=NO configuration file option when used with either ZIPMagic 1.0 or ZIPMagic 98. * AS/400 Client Access The on-access scanner cannot be used with AS/400 Client Access because the Sweep95 VxD is unable to open files stored on the AS/400. Additional information ---------------------- Some of the following information refers to use of the Registry Editor (REGEDT32.EXE). Microsoft has issued the following warning with respect to the Registry Editor: "Using Registry Editor incorrectly can cause serious, system-wide problems that may require you to reinstall Windows 95/98/Me to correct them. Microsoft cannot guarantee that any problems resulting from the use of Registry Editor can be solved. Use this tool at your own risk." * Archive types Archives are not scanned by default. To enable archive scanning, tick the 'Scan inside archives' box within Sophos Anti-Virus. Depending on the number of archives present, scanning time may be increased. Selecting archive scanning enables the scanning of ARJ, BZip2, CAB, CMZ, GZIP, LHA, LZH, RAR, RAR3, TAR, UUE, XSN, ZIP, self-extracting archives of these types, Zipmail files, compressed help and files compressed with MS Compress. Self-extracting archives are only scanned as archives if archive handling has been switched on for that archive type. Otherwise they will be scanned only as executables. If both archive scanning and Macintosh virus scanning are selected BinHex and MacBinary files will also be scanned. Unix ELF files are scanned either when their file extension is in the executables list, or if 'All files' is selected. * Messaging sub-system Forcing the SMTP SMM to send its reports as MIME-encoded attachments is possible. To do this add the following value to the registry: Key: HLM\SOFTWARE\Sophos\Sweep95\SMMs\SMTP.smm Value Name: Mime Encode Type: REG_DWORD Data: 0x00000001 * Improved interaction with files held in off-line storage By default, during immediate and scheduled scans, Sophos Anti-Virus will not retrieve files marked as being held in off-line storage for scanning. This default behaviour can be over-ridden by setting the following value in the registry. Key: HLM\Software\Sophos\ADVANCED\ Value Name: SCAN_FILES_IN_HSM Type: REG_DWORD Data: 0x00000001 * Scanning during an update Sophos Anti-Virus for Windows 95/98/Me scans memory, boot sectors and system files during an update. If file copying is interrupted the process will resume from the last complete file copied. It will not start again from the beginning. Information from previous versions ---------------------------------- 4.7.11 * (DEF 21427) MIME scanning has been improved.
