Block Keeper (BlockKeeper), – a rogue antivirus (clone of BlockScanner, BlockWatcher and SoftVeteran). BlockKeeper installs by taking advantage of poorly guarded systems that appear to have vulnerable backdoors. A quite widespread alternative method of Block Keeper intrusion is online scanners that confuse users by popping up unexpectedly and reporting numerous spyware infections thus trying to have the user download its unregistered copy.
