Summary

Armed with this information, you’re now well on your way to protecting your WLAN from malicious code. The topics I presented in this chapter include:

• Introduction to malicious software

• Explanation of computer viruses, Internet worms, blended threats, and Trojan programs

• The threat from bot software, and spyware

• The emerging problem of viruses on handheld devices

• The problems caused by virus hoaxes

The days when you could leave your antivirus software turned off, or worse, not install any at all, are long gone. The pace of malware development is quickening, not slowing down, and the sophistication of the attacks is increasing. These two trends emphasize the need to be vigilant and to secure your computers.
