What is Protection Booster?

Windows Protection Booster is a fake antivirus program, which imitates the detection of high-risk security threats in order to scare unsuspecting PC users into purchasing a 'full version' to supposedly eliminate them. Computer users should be aware that this program should not be trusted - it is a scam created by cyber criminals who make money from PC users who fall for the fake security warning messages and purchase license keys for this rogue antivirus program. This bogus software infiltrates operating systems using hacked websites, which display a fake Microsoft Security Essentials alert message with the purpose to trick Internet users into downloading and installing Windows Protection Booster on their computers.

After successful infiltration, this rogue antivirus program modifies the registry entries of an affected operating system by disabling execution of installed software, blocking the Task Manager, and configuring itself to start automatically on each system Startup. The aim of Windows Protection Booster is to make your operating system unusable and encourage you to purchase 'ultimate protection' (the 'full version'). Note that paying for this program is equivalent to sending your money and credit card information to cyber criminals. Do not buy this program - it is a scam.

Windows Protection Booster originates from a family of rogue antivirus programs called FakeVimes. Previous variants were named Windows Antivirus Booster and Windows Antivirus Helper. Cyber criminals responsible for developing these bogus programs maintain identical user interfaces and functionality and merely change the name of each variant. To avoid computer infection with these fake antivirus programs, keep your operating system and installed software up-to-date, and use legitimate antivirus and anti-spyware programs. Moreover, Internet users should be aware that online security warning messages reporting security infections and offering download of antivirus programs to clean them, are not legitimate. These malicious pop-ups are used by cyber criminals to distribute fake antivirus programs - do not trust these online messages. PC users who observe Windows Protection Booster scanning their operating systems for security infections should use this removal guide to eliminate this scam from their computers.

How does Windows Protection Booster infect the user's computer?

In the second step of this scam, users are presented with another fake message, which is supposedly derived from Microsoft Security Essentials: "Microsoft Security Essentials Alert. Microsoft Security Essentials detected potential threats that might compromise your privacy or damage your computer. You need to clean your computer immediately to prevent the system crash".

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:

Summary:

The fake antivirus programs (also known as "rogue antivirus programs" or "scareware") are applications that tries to lure computer users into paying for their non-existent full versions to remove the supposedly detected security infections (although the computer is actually clean). These bogus programs are created by cyber criminals who design them to look as legitimate antivirus software. Most commonly rogue antivirus programs infiltrate user's computer using poop-up windows or alerts which appear when users surf the Internet. These deceptive messages trick users into downloading a rogue antivirus program on their computers. Other known tactics used to spread scareware include exploit kits, infected email messages, online ad networks, drive-by downloads, or even direct calls to user's offering free support.

A computer that is infected with a fake antivirus program might also have other malware installed on it as rogue antivirus programs often are bundled with Trojans and exploit kits. Noteworthy that additional malware that infiltrates user's operating system remains on victim's computer regardless of whether a payment for a non-existent full version of a fake antivirus program is made. Here are some examples of fake security warning messages that are used in fake antivirus distribution:

By paying for a license key of a fake antivirus program users would send their money and banking information to cyber criminals.
