win4lin guide 面的东西
Win4Lin installs Windows in a Linux environment, which provides greater virus protection than a
stand-alone Windows installation. Many Windows viruses will have no effect on your system.
One way you can help protect yourself from viruses is to make backups of your Win4Lin
directories. For example, you can use the following command to make a backup copy of your
Win4Lin C: drive (usually $HOME/win):
cd $HOME
tar cvfz win.tgz win
The result will be a compressed tar archive of your win directory stored in the win.tgz file.
The following are some examples of the types of Windows viruses that may or may not affect your
Win4Lin Windows environment:
Boot Sector or Other Boot Time Viruses
Boot sector and boot time viruses have no effect on Windows under Win4Lin because Win4Lin
has no boot sector for Windows. The DOS boot files are read-only and enforced by Linux file
access permissions.
Filesystem Related Viruses
Windows uses filesystems called FAT32 and VFAT. Win4Lin installs Windows files on a
subdirectory of the Linux Ext2 filesystem. Therefore, any virus that depends on the FAT32 or VFAT
filesystem functionality will have no effect.
Executable File Viruses
Windows executable viruses do not affect Linux programs. However, executable file viruses may
still affect your Windows environment, but damage should be limited.
Macro Viruses
Most macro viruses don’t affect Linux applications, so damage is generally limited to Windows.
Macro viruses are still a problem, but you can restrict the damage they cause. Make shared files
un-writable by adjusting Linux file permissions.
3rd Party Antivirus Software and Win4Lin
Please note that if you decide to install a third party Windows-based Antivirus system, there is a
chance that it may damage your Windows installation. It is very important that you first make a
back-up as described above, so that you can restore your installation in case this happens.
NeTraverse always tries to ensure that most current, popular Antivirus software works well under
Win4Lin. If an Antivirus-related Win4Lin bug is found, NeTraverse makes it a high priority to
release an update to fix the problem. A general rule when installing Antivirus software is to make
sure to disable any boot sector scans, as the disk’s boot sector is not accessible to Windows
under Win4Lin and may confuse the software. Again it is highly recommended that you first
back-up your data before installing Antivirus software. |
