The Internet is a great resource for knowledge and entertainment and living without it no longer possible. We use it to gather information and to communicate without any borders. But here is also one of the the main drawbacks: Access to your computer while surfing the Internet is quite easy and spy- or malware can be installed easily. To detect spyware most operating systems like Windows got software coming with it, but unfortunately those packages are outdated and inefficient. Another major disadvantage is that those protection systems are installed on nearly every computer in the world, so programmers of spyware use flaws in that software selectively to place spyware on as many computers as possible.
