How to scan your computer for spyware using Windows Defender
Published: February 13, 2006 | Updated: October 23, 2006
Windows Defender allows you to run a "quick scan" or "full system scan" of your computer. If you suspect spyware has infected a specific area of your computer, you can customize a scan by selecting only the drives and folders that you want to check.
A quick scan checks the places on your computer's hard disk that spyware is most likely to infect. A full scan will check all files on your hard disk and all currently running programs, but it might cause your computer to run slowly until the scan is complete. We recommend that you schedule a daily quick scan. If you ever suspect that spyware has infected your computer, run a full scan.
