Spyware became a matter of public concern regarding privacy on the Internet as a result of its invasion of people's privacy by using information from computer systems without their knowledge or consent.
You can get unwanted software by downloading music, video or games from unfamiliar websites. This can be both spyware and adware in the same time, but not all adware is spyware.
Spyware is also known as spyboat or tracking software, adware, foistware, malware, eulaware, or even crapware.
What is in fact Spyware?
Spyware is a software that collects personal information without people's knowledge or permission and sends it to third parties (other person, company, server). The risk it involves is that sensitive information can be easily misused by unscrupulous individuals or organizations.
What is the difference between adware, spyware and viruses?
While viruses are programs installed onto computers without people knowing it, spyware and adware are programs chosen by people, most of the time undeliberately. It is true that they don't give their consent to have spyware or adware installed, but the presence malicious software in their Pc's is the result of their misinformation.
If someone agrees to have a program installed without reading the license, it means that that person agrees to have spyware or adware on his/her computer.
Adware doesn't behave like a virus or worm: they don't spread themselves using the user's address book, they don't actually damage computers, except from slowing down their performance.
When do spyware and adware infestations occur?
- Most of the times, spyware/adware infections appear as a result of surfing on malicious websites.
- Another method of getting spyware/adware on your computer is to install freeware (programs) that include them (for instance, a free file-sharing program).
- Sometimes you may be tricked to click on a link that installs spyware/adware. Much spyware installs after you click a deceptive link in a pop-up browser window.
For example, a website that is trying to push spyware onto your computer might open a window that looks like a Windows dialog box, and then trick you by installing it when you click the Cancel button to close the dialog box. Other times, spyware pushers will put a fake title bar in an empty window, and install the spyware software when you try to close the window.
