• What is spyware and what does it do?
Spyware is a malicious software program that is installed on personal computers to collect information about the user, their computer and/or browsing habits without their consent. This often occurs when a user visits an unknown website or downloads software online or in an email. Spyware programs can collect various types of personal information, such as Internet browsing habits and sites that have been visited, and can also interfere with the computer in other ways. Loss of computer functionality such as slow connection speeds and changed settings is often a result of spyware. It is important to have a good anti-virus program that protects against spyware or a spyware removal software installed on your computer.
