- Agax v1.0 Manual
-
- ----------------------------------------------------------------------------
-
- Agax
-
- Agax is an antivirus application. It scans your disks and files for
- viruses. It also contains Defender, which is an antivirus extension. Both of
- these use Additives to discover and (in the case of Agax) repair infected
- files. Additives are stored in the folder 'Additives' in the same folder as
- Agax.
-
- The main window of Agax has the title 'Log'. It records Agax's antivirus
- activity - in particular reporting the discovery of infected files, and the
- success it has in repairing them. You can perform operations on the log with
- the File menu.
-
- Agax has two menus with identical contents but different titles - the
- 'Examine' and 'Repair' menus. These both do the same thing (scan for virii),
- except that 'Repair' will attempt to remove viruses from infected files,
- whereas 'Examine' will just report the infection. Some files cannot be
- repaired, and you are given the option of deleting these at the end of the
- scan. Agax displays a progress bar during its scan of a volume. To stop the
- scan, click the close box of the progress bar.
-
- The 'Virii' menu contains a list of the currently installed Additives. You
- can view more information about an Additive by selecting it from this menu.
- You can change when this Additive is used from the window which results.
- There are three checkboxes: 'Examine files for this virus' uses this
- Additive when it is examining; 'Repair files with this virus' uses this
- Additive when repairing; 'Proactively repel this virus' uses this Additive
- in Defender. Changes to the last checkbox will only take effect on restart.
-
- These options as recorded in the preferences. When Agax starts up, it checks
- to see how the list of Additives has changed from last time. If any are
- missing, it will warn you of the fact, and if there are any new ones, it
- will ask you what you want to do with them (enable all or disable all). You
- can change this later through the information boxes described above. If Agax
- can't find its preferences, it tells you and enables all Additives.
-
- Defender
-
- The only available option in the Edit menu is 'Preferences'. Currently,
- this controls only the preferences for Defender. Any changes made here only
- take effect on restart. The first checkbox 'Enable Defender' controls
- whether or not the Defender extension is installed. If the status of this
- checkbox has changed when you close the preferences, Agax will take the
- appropriate action (i.e. create or delete Defender in the Extensions
- folder).
-
- When Defender is enabled, you can choose how it protects your computer.
- There are currently three types of protection:
-
- - 'Examine volumes when mounted'. When a volume is mounted, it is examined.
- If a virus is found you are asked to run Agax on the volume. There is a
- further option under this: 'Simple examination' or 'Thorough examination'.
- 'Simple examination' is quick and will find virii which always live in the
- same place on a volume (such as AutoStart worms ... not that there's an
- Additive for these yet). 'Thorough examination' does a complete scan of the
- volume, as if it was selected from the 'Examine' menu, but without the
- progress bar. As you can imagine this is very slow, so I don't recommend it.
-
- (Note: After startup, all volumes except the system volume will be scanned
- in the method indicated if volume examination is enabled)
-
- - 'Examine applications when launched'. When an application or desk
- accessory is launched, it is examined. If a virus is found, the launch is
- prevented and you are told that the application is infected. Control Panels
- are not examined, as they execute inside the Finder. To catch infected
- control panels (not that I know of any) you would have to use the next type
- of protection.
-
- - 'Examine resource forks when opened'. When a resource fork is opened, it
- is examined. If the file is infected, the open is prevented and you are told
- that the file is infected. If this type is on as well as the examining
- launches type, clean applications will be examined twice (but it doesn't
- take long, so don't worry about it too much). When this type is selected,
- even the Finder's 'Get Info' command will warn you of infection (for
- applications at any rate).
-
- Alongside all of these types of protection there is the option to log when
- the checks occur. Even if these boxes are unchecked, infections will still
- be logged - unchecking them just cuts out the 'Started...'/'Completed ...'
- log entries. Warning: Turning this option on for resource forks is a bad
- idea - resource forks are opened and closed all the time. It will
- significantly slow down your computer, and make the log huge (too big for
- SimpleText) very quickly. The log is also useful for determining the virus
- causing the infection (without running Agax), as the notification message
- does not tell you this information.
-
- Defender's log is called 'Defender Log' and stored inside the System folder.
-
- Defender too keeps track of which Additives are around - newly discovered
- additves are disabled. The Additives which Defender uses are those beside
- the last Agax which was run - so make sure you don't use Agax on a server
- (actually, I haven't tested this - it might actually mount the server during
- startup).
-
- Warnings, bugs, etc.
-
- Warning: Both Defender and Agax make an attempt to guard against themselves
- being infected. Thus you shouldn't fiddle with them - in particular, don't
- unlock Agax, and don't change its memory allocation. This will likely be
- improved and extended to Additives in the near future.
-
- Agax replaces Antigax and GAx Defender - you should delete these and use
- Agax and Defender instead.
-
- System Requirements
-
- Theoretically, Agax should work from System 7.0 up, however Defender only
- works from System 7.5 up. The current version has only been tested on System
- 8.0 and 8.1 (that should probably be MacOS 8.0 ... ), so I really don't know
- about anything other than those.
