What is spyware?

With many types of software that are spread around the internet intended to do harm, it is quite important to take caution when it comes what spyware can do much of harm. Spyware is a term that is used to describe software that performs specific actions, but without getting your permission before using it, such as:
• Advertising.
• Collecting personal information of different people.
• Changing your computer configuration.
Spyware is often related to software that shows advertisements (often named adware) or at other times it is software that follows the trails of personal information.

 Trading tracking for services
What said before doesn’t mean that all software that use ads or software that keeps track of your online activities is bad. For example, let’s say you signed up for a free music service, but by that it means that you are paying for the service by agreeing to get the targeted ads. If you fully understood the terms you agreed to, you may by that have decided that is a fair tradeoff between the two of you.

The recent revelations about the NSA surveillance programme have cause concern and outrage by citizens and politicians across the world. What has been missing, though, is any extended discussion of why the government wants the surveillance and on what basis is it authorised.
