Using a wireless internet network ( Wi-Fi) has many advantages for internet users. It allows you to be able to work in any room of your home and even outside your house and still be able to connect to the internet. Along with the advantages, Wi-Fi also comes with some security issues. If you can pick your Wi-Fi signal from outside your house, that means that others will be able to do the same. Wireless internet users need to take some extra precautions to protect their information from being taken or hacked into by others.
The best way to protect our computer when you have Wi-Fi is to make sure that you have an up-to-date antivirus program installed on your computer. Most anti-virus software will automatically scan your computer to check for any possible threats or viruses. By enabling a WEP or WPA (encryptions on your computer) you can help prevent any intruders from accessing your computer and installing a virus or worm on it. This is very important for wireless internet users as any half-way decent hacker can use your Wi-Fi connection to get into your computer.
