Keep Windows up to date
Since spyware almost exclusively affects Windows-based PCs, it's important to make sure that you keep your operating system up to date. Microsoft Windows Update is the semi-automated system that keeps Windows secure by providing critical patches and security updates, which address vulnerabilities. Get those critical updates installed, one way or another, then you can move on to more advanced security.
Firewall: More than a really cool word
A firewall is a piece of hardware or software that hides your PC from the prying eyes of the Internet. All Internet-enabled PCs have something called an IP (Internet Protocol) address; a unique number that designates through which channels your PC is accessing the Internet. It is very easy for any other Internet user to discover your IP, but your firewall will determine just how much they can do once they've got it. Use Windows' built-in security features, like its firewall and Internet Security and Privacy settings. Delete your Temporary Internet Files regularly. Turn your computer off when it's not being used.
Anti-virus is non-negotiable
Another reality of modern computing: anti-virus software is absolutely, positively necessary. Using e-mail or the Internet without a good anti-virus program running is just too risky. Imagine accidentally clicking on one unwanted spam e-mail and having your computer continually restart itself every 30 seconds, making it impossible to connect to the Internet long enough to download a fix. Powerful, free anti-virus tools are available from Avast.com and Grisoft.com. Both programs are reliable
Before downloading a free program, like a file-sharing client or media player, make sure it's coming from a reputable source. Look for the word “ad-supported” or anything in the program's Terms of Use documentation that mentions data collection for marketing purposes. A quick Web search with the search terms “[product name] spyware” may help you determine if the program has any Spyware associations.
Don't download ripped movies, CDs, PC games, etc.
No, this isn't some ethical tirade against piracy. Rather, pirated games, crack files, and even movies can be easily packaged or archived with Spyware, viruses and worms. Downloading illicit files, particularly over peer-to-peer (P2P) networks like Kazaa or Gnutella, is a risky business. Plus you're stealing, which is unethical.
Stay Informed
Even with an anti-virus/firewall combination protecting your PC, there's no substitute for knowledge. Understanding spyware and learning about the latest and most dangerous threats is the key to staying protected. Spend some time surfing the Web and keep all your software patched and up to date. |
