The source of infection is primarily when the spyware downloads itself. This usually happens when you are downloading from the internet, which means that the Internet is the route of contamination. However, other sources such as storage devices and local area networks are also contributors to this malicious software. It is natural for users not to install any program or utility if they feel that the installation will disrupt the performance of the system. This is why it is necessary for spyware to deceive the user in order to be downloaded onto the system.

Usually spyware loads itself to the systems memory and keeps track of all your internet activities like surfing habits, sites visited and above all secretly monitors your personal information. If your computer gets infected with this virus it can even interfere with your controls and can also install additional software, redirect web browser activity and infect your computer with more viruses and above all divert advertising revenue to third party.

Therefore it becomes necessary to remove such viruses and the effective way of doing this is to download antivirus software’s which are specifically designed to tackle virus related problems.
