- xThe ANTI Virus
-
-
- The ANTI virus first appeared in France in early 1989.
-
-
- Unlike the other viruses, ANTI does not infect the System file. It only
-
- infects applications and other files which resemble applications (e.g.,
-
- Finder). ANTI does not infect document files. It is less contagious than the
-
- INIT 29 virus, but more contagious than the Scores and nVIR viruses. It is
-
- possible for an application to become infected even if it is never run.
-
-
- Due to a technical quirk, ANTI does not spread at all when MultiFinder is
-
- used. It only spreads when Finder is used.
-
-
- There is an error in ANTI which causes it to slightly damage applications
-
- in such a way that Disinfectant cannot perfectly repair them. In other
-
- words, the application as repaired by Disinfectant is usually not identical
-
- to the uninfected original application. The damage is very minor,
-
- however, and in almost all cases it does not cause any problems. If you
-
- experience problems with an application which was infected by ANTI and
-
- repaired by Disinfectant, we recommend that you delete the repaired copy
-
- and replace it by an uninfected original copy. This is good advice in any
-
- case.
-
-
- (For the technically inclined, the error in ANTI is that it clears all the
-
- resource attributes of the CODE 1 resource. Disinfectant has no way to
-
- know the values of the original attributes, so it leaves them cleared on
-
- the repaired application. The only effect of this error is that the repaired
-
- application may use memory slightly less efficiently than the original
-
- version, especially on old Macintoshes with the 64K ROMs.)
-
-
- As with the other viruses, ANTI is non-malicious. It does not attempt to
-
- do any damage other than spread itself. As with all viruses, however, it
-
- can still cause problems.
-
-
- The string “ANTI” appears within the virus, hence its name.
