SpySheriff is malware that disguises itself as an anti-spyware program. SpySheriff is also known as Brave Sentry, Pest Trap, SpyTrooper,[1] and SpywareNo.[2] The program attempts to trick the user of an infected computer into buying the program by repeatedly informing them of false threats to their system.[3] SpySheriff is difficult to remove from an infected computer;[4] attempting to remove it using the "Add/Remove Programs" applet in control panel does not remove all components,[5] and SpySheriff's components may be in the System Restore folders.[6] However, SpySheriff can easily be removed using anti-malware tools.[7]

Websites

SpySheriff used to be hosted at www.spy-sheriff.com. However, this website is now defunct.[8] Several typosquatted websites also attempted to automatically install SpySheriff, including a version of Google.com (oogle.com). As of 2007, these sites no longer distribute SpySheriff.
