Whats the difference between a virus, spyware, Malware, and adware?
Now days the average computer user must be aware of the potential threats their
computer faces each time you connect to the world wide web. It is a dangerous
place for a computer and the security threats are growing everyday. It all so
confusing, viruses, spyware, malware, and adware, just to name a few. Why are
they all so different?
In the old days we used to call everything a virus, however now days we have
more precise names to further categorize them. Below I will show you the
difference between a virus, spyware, malware, and adware.
What is Malware?
Malware is a software program that has bad intentions. It can either be
installed by the computer user accidentally or it can sneak into your computer
through various avenues. Its not the same as a piece of software that by chance
causes harm to your computer, malware is software that has been developed with
the intent of causing problems with your computer.
What is Spyware?
Spyware is a type of malware program that invades your computer and basically
spies on you. There are different types of spyware that collect different
information. A common spyware type is a keylogger which records keystrokes typed
on your keyboard. This is how people lose their bank account details. Other
spyware will record your actions and browsing habits on the internet. Any
information collected by spyware is usually with the intent to sell.
What is Adware?
Adware is another form of malware and is exactly as the name suggests, software
with advertising. Adware can be downloaded and sometimes included in free
programs. For example Windows Live messenger and Yahoo messenger contain adware.
Although some programs give the option not to install the extra adware, others
seem to sneak it in without permission.
What is Virus?
A virus is a small program designed to infect your computer and cause errors,
computer crashes, and even destroy your computer hardware. Unlike spyware, a
virus can grow and replicate itself. It can also travel from one computer to
another via an internet connection. Of course you can get viruses from discs
with virus infested files stored on them, however the internet is the most
common entry point. Some common symptoms of a virus are emails being sent to all
contacts when you didn't send them, being taken to webpage's that you didn't
choose, or being told you have a virus and to download a program to fix it.
