SpySheriff
SpySheriff is malware that
disguises itself as an anti-spyware program. SpySheriff is also known as
Brave Sentry, Pest Trap, SpyTrooper, and SpywareNo. 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. SpySheriff was initially difficult to remove from an infected computer and is difficult to remove manually. Attempting to remove it using the "Add/Remove Programs" applet in control panel does not remove all components, and SpySheriff's components may be in the System Restore folders.[ SpySheriff can be easily removed using anti-malware tools.
