Security Cleaner Pro removal instructions

What is Security Cleaner Pro?

Security Cleaner Pro is a rogue antivirus program, which aims to trick unsuspecting PC users into purchasing a license key in order to remove supposedly-identified security infections. In fact, no security infections reported by this program are genuine - Security Cleaner Pro mimics the detection of various malware and viruses in order to scare PC users into believing that their computers are infiltrated with high-risk security threats. Note that this rogue software generates an identical list of supposedly-detected security infections on all computers infiltrated. This bogus program is developed by cyber criminals and distributed using 'exploit kits', which infiltrate users' computers via security vulnerabilities detected within outdated software. Common sources of fake antivirus programs such as Security Cleaner Pro are malicious websites, drive-by downloads, and infected email messages.

After successful infiltration, this bogus software modifies registry entries of the infected operating system and configures itself to launch on each system start-up. Furthermore, this fake security scanner hijacks Internet browsers (Internet Explorer) and blocks execution of installed software. In addition, this rogue program makes operating system modifications, disables the Task Manager, and continually generates fake security warning pop-ups. For added authenticity, cyber criminals responsible for developing this rogue program have created a professional user interface. In fact, it is a scam. Computer users should not be tricked into buying the fake license key. The correct way to deal with Security Cleaner Pro is to remove it from your PC. A previous variant developed by these cyber criminals was named Sinergia Cleaner.

Security Cleaner Pro has no virus definition database or virus scan engine - it is merely a fake antivirus program created by cyber criminals with the sole purpose of tricking PC users into purchasing a fake license key. Note that by purchasing this bogus software, PC users not only send their money to cyber criminals, but also divulge their banking information - this could lead to further thefts from their accounts.
