Spyware, Adware & Viruses
Many computer security experts believe the greatest threat today comes not from viruses sent as email attachments but from spyware added to unsuspecting users' PCs while they browse on the Web. Spyware, as the name suggests, is any technology that aids in gathering information about a person or organization without their knowledge, usually for a malicious purpose. Some distinctions may be made between spyware and adware. Adware is software that displays advertisements on a user's PC while a program is running, but is also capable of tracking a user's personal information and passing it on to third parties, without the user's authorization or knowledge.
A common misconception is that antivirus and firewall software can catch all spyware and adware. Unfortunately, this is not so. Computer users need to be responsible for checking for spyware on their PCs by utilizing software that scans for and removes spyware and adware.
The following are examples of free spyware removal tools available:
