4. Spyware programs aren't viruses, so installing antivirus software doesn't fully protect you from spyware.
5. Many spyware programs communicate through the same Internet port (80) as general Web traffic, thus making it very difficult to block data transmission using a firewall.
7. If you are responsible for IT in a corporate environment, seriously consider the use of products such as Websense Enterprise which automatically prevents users from downloading and installing programs which contain spyware. It will also ensure that any spyware application already installed on the user's PC is unable to run, and thus stops it from transmitting confidential information.
