Known by several different names, from spyware to malware or internet parasites, surveillance applications are installed on your system to monitor your internet activities and reveal your surfing patterns and purchasing habits. Spyware also extracts email addresses, hijacks browsers and records credit card numbers, bank accounts and password information.

The information gathered by a spyware application is sent back to the intruder who typically uses it to bombard you with pop up and email advertisements. More serious consequences occur when credit and bank information is obtained by spyware and used for identity theft or credit card fraud. Spyware also compromises the fast and efficient functioning of your computer as it builds up and uses the system's resources. Computer crashes occur with extreme infections which can lead to malfunctions in your registry keys and memory.

To avoid spyware and adware and protect your privacy users must be cautious when surfing the internet. Beware of freeware and shareware programs as they usually install spyware as well, without the user's knowledge. Install and regularly use a good spyware scan and removal tool. An effective anti-spyware program will detect and remove all possible infected files.

The scanner should perform a deep system scan in order to catch files infected that usually go unnoticed.

Most spyware scanners have a removal feature as well but for those that do not a list of detected spyware files is still complied at the end of the scan. This list given by any spyware tool tells the details of that particular spyware as well as its location on your computer. If there is not removal feature on your program you can try manually deleting them.
