It is useful to deploy technology such as firewalls to control unwanted communication with the internet. Ensuring that the security settings on web browsers are turned on and kept to a high setting will also provide a measure of protection. Spyware and other kinds of malicious code are often designed to exploit security vulnerabilities. Whenever these are discovered in software, the manufacturers issue security patches for users to download. It is important to keep up to date with the latest patches for whichever browser is being used.

However, the most effective way to protect against spyware is to use an integrated security solution to stop spyware both at the email gateway and at desktop level. Using software that protects at all levels in this way is vital.
