USA Today is reporting on a new variant of scareware that locks users out of nearly all applications until they purchase the disreputable product. Once their PCs are infected with the malware, the only program users can open is Internet Explorer, so they can navigate to the site and make a purchase. It looks similar to the fear-based promos for Virus Remover 2009, SpywareGuard 2008, XP AntiVirus and other worthless security products, but goes a step further by locking out access to all other applications.
