Java applets
|
|
Java applets allow Web developers to create interactive, dynamic Web pages with
broader functionality. They are small, portable Java programs embedded in HTML pages
and can run automatically when the pages are viewed. Malware authors have used Java
applets as a vehicle for attack. Most Web browsers, however, can be configured so
that these applets do not execute - sometimes by simply changing browser security
settings to "high."

Joke programs
|
Joke programs are considered relatively harmless and are often designed to annoy
or make fun of users. They do not infect files, cause damage, or spread to other
systems.
Many joke programs are designed to cause unnecessary panic - especially those that
cause computers to behave as if something has been damaged. Abnormal system behaviours
caused by joke programs include the closing and opening of the CD-ROM tray and the
display of numerous message boxes.
