Spy Sweeper is proprietary software sold by Webroot Software, which detects and removes spyware, and viruses (with optional AntiVirus component) on personal computers that run Microsoft Windows. If the end user also purchases the AntiVirus component, the software will install itself under its official name "Webroot AntiVirus with AntiSpyware".
Spy Sweeper examines files on a computer's hard disk drive
, as well as objects in memory, the Windows registry
], and quarantines any suspicious objects it finds. Spy Sweeper runs continuously while the computer is in operation, monitoring to warn the user of programs being set to start automatically, suspicious programs running, malicious website cookies, unwanted Internet Explorer
changes, known adware websites, suspicious executable files, ActiveX
installations and changes, and changes in system services. It is normally purchased as a yearly subscription; some broadband services, such as MSN Premium
, also offer rebranded versions of Spy Sweeper as part of their subscription.
Webroot offers two versions of Spy Sweeper: a zero-cost 'spy scan' offering real-time protection
from spyware, and a full version that allows for the removal of spyware. Licenses for the full version cost around US$30
each, which can be used for one year on one computer, or $40 for two years. Webroot also sells multiple-license subscriptions, allowing users to install their product on multiple computers using a single subscription, by purchasing either single-user
, three-machine, or enterprise
