Anti-spyware Tips

Hints for keeping spyware off your machine:

Keep your system -- including all anti-viral and anti-spyware packages -- up to date. New spyware comes out every day. Un-patched, un-updated systems are simply asking to be infected. Update the operating system, too. If you don't have anti spyware software, click here right away! This will be a great start to protecting your computer.

You can have Windows handle operating system updates automatically. For example, in Windows XP, right-click on My Computer > Properties > Automatic Updates > Keep My Computer Up To Date.

If using Microsoft's Internet Explorer, turn off its ability to run scripts without your permission: In IE, click Tools > Internet Options > Security. Select the Earth icon under "Select a Web content zone," and then Custom Level. Disable "Download unsigned ActiveX controls," "Initialize and script ActiveX controls not marked as safe," "Active scripting," and "Scripting of Java applets." Then set Java permissions to High Safety.

There's a downside to this, alas: with scripting disabled, some of your favorite Web sites -- or even some trusted intranet sites -- may no longer be usable. But that problem is easily fixed. In IE go to Tools > Internet Options > Security > Trusted Sites > Sites and enter the URLs of known safe sites requiring scripting, one at a time. Uncheck "Require server verification" for all sites in this zone, then click on OK.

Voila: You're protected where you need to be while totally compatible with scripting on trusted sites. Cool.

You'll want to control what gets started when Windows starts up, as both some viruses and some spyware like to plug themselves into the registry or otherwise run at startup. The free Spybot software does a good job of protecting the startup routine well.

Although you can practice safe computing, using every precaution and proactive action imaginable to prevent spyware problems on your machine, chances are you will make a mistake and a piece of spyware will make it onto the system. You can easily remove most spyware by using one of the above mentioned anti-spyware products.

Another way to protect yourself is to prevent spyware from doing its job of transmitting data off the system.

That's where a decent firewall comes in.

When you, as a network manager, are called upon to disinfect a user's machine of spyware, reach for and install a few of the listed anti-spyware programs. Make a full backup of the system in question. Run at least two of the anti-spyware programs. Follow the deletion advice of these programs -- that's why you made full backups, after all.

Just a personal anecdote: my nine year-old son uses my wife's machine, goes to a bunch of game sites and downloads everything that's not nailed down. My wife hits shopping sites mere mortals hadn't even thought could ever exist. My daughter has hit every teen site in existence.

I have one or two pieces of spyware to clean up each week. My wife has totaled just shy of 2,000 pieces of the stuff. Amazing.
