Worms are self-contained and are able to spread without hitching a ride
on something else and without human intervention (such as opening an
email). A trojan (short for Trojan Horse) is a program that
masquerades as something useful or entertaining but also contains
instructions to do something else behind the scenes. This could be to
allow the writer control over your machine (known as opening a back
door) or to steal data or passwords but is rarely pleasant or it would
not need to be hidden. Back Orifice and SubSeven are among the best
known trojans.
What Is Spyware?
Spyware is Internet jargon for Advertising Supported software (Adware).
It is a way for shareware authors to make money from a product, other
than by selling it to the users. There are several large media companies
that offer them to place banner ads in their products in exchange for a
portion of the revenue from banner sales. This way, you don't have to
pay for the software and the developers are still getting paid. If you
find the banners annoying, there is usually an option to remove them, by
paying the regular licensing fee.
While this may be a great concept, the downside is that the advertising
companies also install additional tracking software on your system,
which is continuously "calling home", using your Internet connection and
reports statistical data to the "mothership". While according to the
privacy policies of the companies, there will be no sensitive or
identifying data collected from your system and you shall remain
anonymous, it still remains the fact, that you have a "live" server
sitting on your PC that is sending information about you and your
surfing habits to a remote location.....
