Run an anti-spyware program to scan your system for spyware and remove it. You can use Windows Defender, a free, built-in utility that comes with Vista or use a third-party antispyware program. Review the software files that are identified as possible spyware, and then follow the antispyware program’s instructions to select and delete suspicious files.
While many antivirus programs can remove some spyware, spyware differs from viruses, so it is recommended that you run an antispyware program specifically developed for this purpose.
