What is Ultimate Booster?
Windows Ultimate Booster is a rogue antivirus program, which indicates various non existent security threats in order to scare PC users into believing that their computers are infected with high-risk malware. The main purpose of this malicious behavior is to sell a license key for this fake antivirus program. PC users should be aware that paying for the full version of Windows Ultimate Booster is equivalent to sending their money to cyber criminals - they will lose their money and their computers will remain infected with this bogus software. After successful infiltration, this rogue program modifies the registry entries of an infected operating system, disables execution of installed software (including Internet browsers), blocks the Task Manager, and configures itself to start automatically on each system Startup.
This fake security scanner originates from a family of fake antivirus programs called FakeVimes. Commonly, cyber criminals responsible for creating such rogue programs use fake online security scanners in order to trick PC users into downloading their bogus software. Fake online security scanners are malicious pop-up ads, which mimic the detection of security infections and offer installation of security software, supposedly to eliminate them. Other known infiltration methods are infected email messages, malicious websites, and P2P networks. Do not trust Windows Ultimate Booster - it is a scam.
Windows Ultimate Booster is identical to previous variants named Windows Efficiency Kit, Windows Prime Accelerator, and Windows Prime Booster. Cyber criminals responsible for developing these fake antivirus programs employ identical user interfaces and functionality, the only difference being the name of their rogue software. Users who have already paid for the 'ultimate protection' (full version) of Windows Ultimate Booster should immediately contact their credit card company and dispute the charges, explaining that they have been tricked into purchasing a fake antivirus program. To avoid installation of such fake security scanners, PC users should not trust online pop-up messages offering installation of antivirus programs.

After removing this rogue software, reset your Hosts file. Do not skip this step since Windows Ultimate Booster modifies your Hosts file 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:
