Activate protection systems.
If your operating system comes standard with a built-in firewall, spam blocker, anti-virus software or other security application, be sure that it’s activated. Your Internet service provider may provide an e-mail spam filtering service that should also be turned on.
Upgrade your protection.
Using security software won’t help if it’s not up to date. Be sure that you are using the latest versions of spam, spyware and virus-detection software. The most current software will be ready to handle the most current on-line threats. Also remember to renew subscriptions if the software registration expires at some point.
Use anti-virus software.
You should always have anti-virus software on your computer. These programs scan all files that are downloaded from e-mail or opened from the hard drive to ensure that they are safe from malware before use. When these programs detect a virus, they are able to isolate and destroy it so it does not infect your computer.
Use anti-spyware programs.
Just like anti-virus programs, spyware protection is also necessary. These programs scan your computer for spyware, browser hijackers and other malicious programs. Both free and commercial anti-spyware products are available.
Set both your operating system and security programs to update automatically. Your virus-detection software needs to adapt as new threats become known. Allowing the software to do automatic updates will ensure that you always have the highest level of protection
Use a secure browser.
If you use an older version of Windows, upgrade your browser to Internet Explorer or Firefox . Both of these browsers have built-in features to detect on-line threats.
