- xThe CODE 252 Virus
-
-
- The CODE 252 virus was discovered in California in April, 1992.
-
-
- The virus is designed to trigger if an infected application is run or an
-
- infected system is started up between June 6 and December 31 of any
-
- year, inclusive. When triggered, the virus displays the following
-
- message:
-
-
- You have a virus.
-
- Ha Ha Ha Ha Ha Ha Ha
-
- Now erasing all disks...
-
- Ha Ha Ha Ha Ha Ha Ha
-
- P.S. Have a nice day

-
-
- Despite this message, no files or directories are deleted by the virus.
-
- However, a worried user might turn off or restart a Macintosh upon
-
- seeing this message, and this could corrupt the disk and lead to
-
- significant damage.
-
-
- Between January 1 and June 5 of any year, inclusive, the virus simply
-
- spreads from applications to System files, and then on to other application
-
- files.
-
-
- Due to errors in the virus, it only spreads to new applications under
-
- System 6 without MultiFinder. The Finder also usually becomes infected.
-
-
- Under System 6 with MultiFinder, the virus infects the System file and
-
- the “MultiFinder” file, but it does not spread to new applications.
-
-
- Under System 7, the virus infects the System file, but it does not spread
-
- to new applications. A bad error in the virus can cause crashes or
-
- damaged files under System 7.
-
-
- Under any system, the virus infects the System file, and it can and will
-
- trigger the display of the message.
-
-
- The virus contains a number of additional errors which could cause
-
- crashes, damage, or other problems on any system.
