ZeroSpyware Free Scan will scan your computer to check for any spyware that might have been installed. Some spyware can be quarantined so that you can see whether any other software depended on it. Once you are satisfied that it is not needed you can then delete them permanently. Without any option to update the spyware that ZeroSpyware recognises this is best used as a one off scanning utility.

The free version of this anti spyware package gives you a basic scan of your computer; the full version offers better support and more frequent updates
