Malware is also a horrible nightmare for everyone. Here we'll inform you about malware.

Malware is short for malicious software, computer software that is designed specifically to damage or disrupt a system or computer, such as a virus or a Trojan Horse. The better known types of malware are viruses and worms and are known for the manner in which they spread harm rather than any other behavior.

Another type of malware is spyware. Spyware is computer software that is installed onto a computer without the user's consent to take partial control over the computer and "spys" on their personal information such as Internet habits or even worse--their passwords that they enter on the computer.

Another type of malware is adware. Adware is advertising-supported software that plays, displays, or downloads advertisements. A example of this are pop-up ads. It happens when certain web sites open a new window to display advertisements.
