Even though I have the information in several articles on my site, I still
frequently get asked for recommendations for security products. I got another
such request just yesterday, as a matter of fact.

What people want is a silver bullet. The ideal would be one package
to install or one thing to do that will keep them from getting infected with
malware, and fix everything if they do.

There’s no such beast.

In fact, I explicitly recommend against security suites: those big bundles
of software that try to do everything: firewall, anti-virus, anti-spyware and
sometimes even more. The problem is while they may do one thing well, they
often fail miserably at others. And to be honest, I hear more complaints from
suite users than from any others.

So what do I recommend?

First realize that the single most important security device on your
computer is sitting at the keyboard; it’s you. And that means two things:
taking responsibility for the security of your PC, and avoiding risky

As for specific security tools, the four basics are:

  1. I recommend you have a firewall. A router is best, but turn on the Windows
    firewall if nothing else. I’m not a big fan of other, larger, software

  2. I recommend you keep your machine up to date. I don’t care how, but you
    simply must. Windows Automatic Update is what I use and recommend.

  3. I recommend that you have a good, stand-alone anti-virus product installed,
    and that it either scan in real time, or nightly, and that it update its
    database of virus definitions every day. I happen to use Computer Associate’s
    eTrust Anti-Virus, but there are several other good packages out there as

  4. I recommend that you have a good, stand-alone anti-spyware product installed
    and running, and that it too update its database of known spyware every day. I
    happen to use Microsoft’s Defender.

That’s what I consider a minimum recommended setup. But don’t let it lull
you into a sense of complacency. That device behind the keyboard – you – can
still be used to bypass everything. In fact that’s what many viruses and
phishing attempts count on.

And because I know that people will mention it, of course you could switch
to a Mac or Linux. While that’s not 100% bullet proof, it’s also a topic for
another day.

As I said I have several article on the site on this topic, including links
to some of the alternative anti-virus and anti-spyware programs that I either
recommend or have heard good things about. Links to those articles are in the
show notes.

  1. To protect my computer I use Pc Guard.
    Is a microchip that doesn’t allow any changes on my computer without my authorization.
    I don’t know if I’m allowed to leave the web page, if not, I apologize and ask you to please remove it.

    I’ve being using it for almost 2 years now, and haven’t had any problems or surprises.

    I would like to hear your comments on the subject
