Anti-Spyware Information and Software

Frequently Asked Questions

If you have a Mac, do you need to worry about spyware?

Yes. While Spyware predominantly targets Windows systems, increasingly there are reports of spyware that targets Mac OS and OS X, Safari, Quicktime and even iTunes. The preventative steps recommended here are a good idea for users regardless of platform.

Are spyware and computer viruses the same thing?

No. The University of Wisconsin, Milwaukee, website explains it well: "...Viruses are typically spread from one host computer to another, to damage systems and networks. They do this, either through using so much of the resource that traffic is at a standstill, or they may simply damage or delete necessary system files. Spyware writers on the other hand certainly want to get their software installed on as many computers as possible, but ultimately they are after browsing information. This information can then be sold to advertisers and marketers who charge companies to more accurately target chosen demographics. When systems are adversely affected by the software's presence, the information collectors don't get good data. However, the lines between viruses and spyware are blurring as more and more blended threats are being created. Spyware and viruses increasingly use one another's tactics, such as browser vulnerabilities, to achieve their goals..."

How do adware/spyware removal tools work?

Most of the removal tools act like antivirus tools. They maintain a library of spyware filenames and registry keys, and search for and remove them from your computer.

Is all spyware bad?

According to CNET, spyware/adware offers varying degrees of annoyance. Some adware merely delivers a small ad banner in a program's interface. Other types of aware launch pop-up browser windows over pages you're currently viewing. The worst kind of spyware gathers personal data about you and sends it to a central server.

How often should you run your anti-spyware programs?

There are two answers to this question. Some anti-spyware software includes a "real time" scanner which will watch for new spyware. If your software has real time protection you should enable this feature. Anti-spyware software can also search your computer for new spyware. It is a good idea to run this scan once a week.

Which products are most effective?

ITS supports the use of Windows Defender software on a regular basis. In addition to using Microsoft's Windows Defender , ITS recommends that you use mulitple anti-spyware applications, such as Spybot Search and Destroy. These additional pieces should be used a couple of times a month to catch any spyware that Microsoft's AntiSpyware might have misssed.
