Spyware – also named Malware or Adware – are malicious software programs, which most of
time get installed on your computer without your knowledge. These programs are capable of doing many outrageous, sinister things to your computer such as changing computer settings, tracking your online behavior, monitoring and controlling your computer, recording your keystrokes, displaying unwanted advertisement and reporting needed information back to
person behind it.
The main types of Spyware are:
Key loggers: This type of Spyware copies everything you type to a file and send it to
hacker. The more sophisticated type, which is used for identity theft, copies
information you provide when you are connected to a secure website.
Browser hijacker: It modifies browser settings without your permission. This Spyware is capable of changing your start page, search page, search tool bar and redirect your url to specific pages.
Email redirector: Surreptitiously copies all your incoming and outgoing emails and sends to
hacker.
Dialers: This spyware install themselves to your dial-up settings and dials numbers without your knowledge, often to out of country numbers.

Why my antivirus program does not block a Spyware?
Although, Spyware uses same tactics like “Trojan” virus, technically it is not a virus. A virus is a program written to create trouble or possibly harm your computer system. Viruses are capable of replicate, evolve and cause severe damages to your computer files, registry or even hardware. Spyware, on
other hand, does not harm your computer intentionally. Any nuisance like system slow down is
collateral damage, which occurs while
Spyware serves its mission of monitoring your activities and making unwanted changes to your user experience.
People rarely read
fine prints of
user agreements while downloading a file, a program, a game or other free stuffs from
Internet. Unethical sites use this to their advantage and add tiny Spyware with
file you are downloading.
The anti-virus programs can not be sure, whether this program is installed deliberately by you or it’s a malicious Spyware. This makes identifying and blocking a Spyware difficult for an Anti-virus program. However, things are started to change! Major anti-virus companies are planning to integrate anti-spyware programs to their existing products very soon.
