As the technology has advanced, so has the threat to the security of our systems. We are installing more powerful and authenticated anti-viruses these days, but the threat to damage our system does not seem to be halting.  As more and stronger anti-viruses are developed, so are the forms of the viruses. Every day, we come across a new form of virus that may cause damage to our PC and new software to get rid of them.

Most of you would have come across a situation when you observe some unusual activity in your system, something like missing icons on the desktop or unexpected pop-ups. This is one of the most common issues these days.  If you have encountered any such situation, there is likelihood that your PC may be infected by Spyware.

Spyware is nothing but software that finds out a hideous place in your PC and then attacks the most important areas of your system. Its only motive is to harm you in all possible way. 

How does it harm you??? Well, there are many ways; depending for what purpose it is developed. One of the most common among them is spreading your personal information for gaining some financial profits.

And who are the people who would actually steal your personal information? Well, they can be:

  1. The creator of the software
  2. A hacker
  3. A 3rd party who would want to use your personal information to get profited.

And how does they benefit???? There are several ways:

  1. Your browsing activity can be tracked and then hacked. This will cause a redirect of a particular website to market it.
  2. Simply misusing your information and causing a threat to personal security information as well as causing damage to your system.

Spyware is a program that is created with the basic motive of stealing the user’s personal information like security information, personal files and folders. The very word itself identifies that it is spying software. This means that a spyware can cause much more damage than what malwares and virus can……….

The strange thing about spyware is that they can hide themselves very efficiently even at the time of detection. Spyware blend themselves into the system with names that may appear too familiar to detect. So how the spyware does not allow any anti-spyware to detect??? There are two ways in which they can be done:

  1. The spyware encrypts in the code/data to allow avoid being detected. They also keep on changing their file per installation.
  2. The spyware tries to kill the anti-spyware process, and thus disabling them.

Do you know???

Gator and eZula are some of the most popular spyware.

Mostly you will be attacked by a spyware in the form of software. However there are some which may be present in the form of hardware too.
