-
-
-
- Disinfectant is fully compatible with System 7 and Mac OS 8, including
-
- virtual memory, 32 bit addressing, and file sharing.
-
-
- Disinfectant is also compatible with the Power Macintosh.
-
-
- Leave the Disinfectant INIT in the Extensions folder. Do not move the INIT
-
- to the System Folder. The “Install Protection INIT” command installs the
-
- INIT in the proper location in the Extensions folder. Do not move it.
-
-
- If you try to repair an infected file, Disinfectant may tell you that the file
-
- is busy and recommend that you either restart using your “Virus Tools”
-
- or emergency startup disk and try again or “rebuild the desktop.”
-
- Restarting using your “Virus Tools” or emergency startup disk was
-
- discussed in the “Quick Start” section above. Rebuilding the desktop is
-
- discussed in the “Problem Clinic” section below.
-
-
- You should also be aware that System 7 is completely immune to the
-
- “Desktop file” viruses (WDEF and CDEF). These viruses never activate,
-
- spread, or cause any damage under System 7. Both hard disks and floppy
-
- disks are immune to these viruses under System 7. Since the Disinfectant
-
- INIT detects and blocks viruses when they first try to attack your
-
- system, and since the Desktop file viruses never attack under System 7,
-
- the Disinfectant INIT will not detect them under System 7.
-
-
- System 7 hard drives, however, often contain an old System 6 format
-
- Desktop file. If you restart using an infected System 6 startup floppy,
-
- this file can and will become infected by WDEF or CDEF. The virus will
-
- only be active, however, when you start up your Mac with System 6. The
-
- proper way to protect against this problem is to install a copy of the
-
- Disinfectant protection INIT in your System 6 System folder.
-
-
- You should also be aware of a problem with System 7’s file sharing
-
- feature. If you share a folder and permit write access to it by granting
-
- the “make changes” privilege with the “Sharing” command, it is possible
-
- for files in the shared folder to become infected by a virus over the
-
- network, even if you have the Disinfectant INIT installed on your Mac. The
-
- INIT will, however, prevent the virus from spreading to your non-shared
-
- folders. It will also completely block any attempt by the virus to execute
-
- its viral code on your Mac or cause any damage to your Mac.
-
-
- We have always had the problem of viruses spreading over a network to
-
- files in writable folders on dedicated AppleShare file servers. With
-
- System 7’s file sharing, this has now also become a problem on personal
-
- Macs.
-
-
- Virus infection over the network is only one of many serious security
-
- problems with writable shared folders. Writable shared folders are
-
- inherently insecure, and no kind of anti-viral or other security software
-
- can prevent damage to their contents. To minimize these problems, we
-
- recommend that you limit write access to your shared folders to only
-
- trusted individuals. Never grant write access to guests (“any user”). The
-
- only way to eliminate the problems completely is to never grant the
-
- “make changes” privilege to anyone except yourself.
