What is Accelarator Pro?
Windows Accelerator Pro is a fake antivirus program that mimics the detection of various high-risk malware infections in order to scare PC users into purchasing the 'full version'. This rogue software imitates a legitimate antivirus program and suggests that this is the only program capable of removing the supposedly 'detected' security infections. In fact, no security threats indicated by this bogus program actually exist on your computer - Windows Accelerator Pro is a scam created by cyber criminals. This program is distributed using malicious or hacked websites, which display fake online security warning messages to trick Internet users into downloading this rogue antivirus program.
After successful infiltration, this fake antivirus software modifies the registry keys of an infected operating system and configures itself to start automatically on each system startup. Moreover, this fake security scanner blocks execution of installed programs and the Task Manager. To further scare computer users into believing that their operating systems are infected with Trojans and viruses, this fake program generates various security warning messages. Windows Accelerator Pro originates from a family of fake antivirus programs called FakeVimes. Do not trust this program or pay for "ultimate protection" (the full version). Paying for this program is equivalent to sending sending your money to cyber criminals.
Windows Accelerator Pro is identical to previous variants named Windows Premium Shield and Windows Efficiency Console. Cyber criminals responsible for creating fake antivirus programs from the FakeVimes family have updated their bogus software to block users' desktops. This behaviour is similar to ransomware infections. To protect your system from rogue antivirus programs such as these, keep all installed programs up-to-date and use legitimate antivirus and anti-spyware software. Users who have already paid for the license key of this bogus software should contact their credit card companies and dispute the charges, explaining that they have been tricked into purchasing a fake antivirus program. Use this removal guide to eliminate Windows Accelerator Pro from your computer.

After removing this rogue software, you should reset your Hosts file. Do not skip this step since Windows Accelerator Pro modifies your Hosts files, and you will encounter browser redirect problems if malicious entries are not eliminated.
The Hosts file is used to resolve canonical names of websites to IP addresses. When it is changed, the user may be redirected to malicious sites, despite seeing legitimate URLs in address bar. It is difficult to determine sites are genuine when the Hosts file is modified. To fix this, please download the Microsoft Fix It tool, that restores your Hosts file to the Windows default. Run this tool when downloaded and follow the on-screen instructions. Download link below:
