SpySheriff[a] (also known as BraveSentry 2.0, among other names) is malware that disguises itself as anti-spyware software.

It attempts to mislead the user with false security alerts, threatening them into buying the program.

[4] Like other rogue antiviruses, after producing a list of false threats, it prompts the user to pay to remove them.

However, SpySheriff can be removed by an experienced user, antivirus software, or by using a rescue disk.

SpySheriff was hosted at both www.spysheriff.com and www.spy-sheriff.com,[6][self-published source] which operated from 2005 until their shutdown in 2008.
