Free Spyware Scan - Your Friend or Foe?

Spyware is a sneaky program that is developed and used for different purposes.  It is typically distributed via freeware and shareware programs which are freely available for download on the internet.  The most common purpose of spyware is to track a user's internet activity, a characteristic found in adware programs.  In this scenario, it collects information about the web sites you visit such as the pages viewed and how long you browsed a particular site.  The data is then stored by the spyware application and sent to the creator.  While this data is often used merely for targeted advertising campaigns, many users view this as an invasion of privacy since the programs are usually downloaded without their knowledge or consent .  In most instances, spyware has some type of negative impact whether it's bombarding your screen with unwanted pop-up ads or slowing down the performance of your computer. 

Apart from being a major distraction in the way of targeted advertising and spam campaigns, spyware may also be used maliciously to commit more serious internet crimes.   These programs are often developed by members of the hacking community, individuals who are knowledgeable enough to make them capture your email passwords, credit card numbers and bank account details.  This is typically done by a type of spyware that logs keystrokes as a user inputs this information into a secured online form.  The personal data can then be used by an intruder to  conduct internet scams or major criminal offenses such as identity theft.  For this reason, it is very imperative to secure your computer with some type of anti-spyware solution.

Reliable Scanners
