Run a Windows Defender Scan


Spyware and adware cause pop-up ads to appear on your screen or
track your online activities. With the amount of spyware and adware
attempting to download to your computer, an anti-spyware/adware
program is a must-have security tool. If you don’t guard against these,
those annoying pop-ups will be the least of your problem. Eventually,
these programs will slow your computer performance to a crawl.

Several good free programs are available, or use your operating system’s
tools (such as Windows Defender, in Windows Vista). With some pro-
grams, you may need to purchase a subscription to get automatic
updates. As with anti-virus software, you can set up anti-spyware/
adware to run scans automatically at a specific time.

If you use Windows Defender to detect spyware, you must run a scanof
your computer system on a regular basis, which searches your computer
for any problem files. You set Windows Defender to run scans automat-
ically, or you can manually run a scan at any time. To adjust these set-
tings, follow these steps:


  1. Choose Start➪All Programs➪Windows Defender.


2.In the resulting Windows Defender window, click the
down-pointing arrowon the Scan button (if you click the
Scan button itself the scan begins). (See Figure 15-8.) In
the resulting menu, choose one of three options:


  • Quick Scan:This runs a scan of the likeliest spots on
    your computer where spyware might lurk. In many cases,
    this quicker scanning process finds most, if not all, prob-
    lems and is good choice for a daily automatic scan.
