System Protection Tools virus

Also Known As: System Protection Tools Rogue
Damage level: High

What is System Protection Tools?

System Protection Tools is a creation of Internet criminals - malicious software, which imitates a legitimate antivirus program and advises PC users to purchase a license key in order to remove 'detected' security infections. In fact, this program is rogue and has none of the features required of a genuine security suite, such as a virus definition database and a virus scan engine.

System Protection Tools rogue program

This bogus software uses falsely-generated security scans and warning messages to scare you into believing that your PC has severe security infections. In fact, the files indicated as malware are generated by System Protection Tools and are harmless.

The main purpose of creating the entries is to mimic their detection as malware during the fake security check-up. This malicious software 'detects' identical security threats on each PC that it infects.

System Protection Tools is derived from a fake antivirus family called 'FakeVimes', and a previous variant of this program was called Best Antivirus Software. The programs from this family use the same user interface and are distributed with a similar misleading strategy.

This fake security program is promoted via fake online security scanners, which are employed within misleading websites. When you enter such a website, a pop-up window appears on your screen, imitating a security check-up.

This results in the 'detection' of various malware, and you will then be asked to download and install System Protection Tools to eliminate them. Do not trust the online security scanner or messages reporting that your PC is infected with viruses.

Commonly, these scans and warning messages are used to distribute rogue antivirus programs such as System Protection Tools. The user interface of this program closely resembles that of Microsoft Security Essential (a free legitimate antivirus program), and therefore, you should not mistake these programs.

Microsoft's legitimate version will never ask you to pay money to remove detected security threats. If you have already paid for System Protection Tools, contact your credit card company and dispute the charges, explaining that you have been tricked into buying a fake antivirus program called System Protection Tools.

Use this removal guide to eliminate this rogue antivirus software from your PC.

After saving the file to your desktop, double click it. In the main HijackThis window click the “Do a system scan only” button. Select the following entry (place a tick at the left of the entry):

O4 – HKCU\..\Run: [System Protection Tools] “%AllUsersProfile%\\_.exe” /s /d

After selecting the required entry, click "Fix Checked". After this procedure you can close HijackThis and proceed to the next removal step.

5. Download legitimate anti-spyware software to fully remove System Protection Tools from your computer.

6. After removing System Protection Tools, reset your Hosts file. Do not skip this step, since this fake program modifies your Hosts file and you will encounter browser redirect problems.

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 websites, despite observing legitimate URLs in the address bar.

It is difficult to determine if a website is genuine when the Hosts file is modified. To fix this, please download the Microsoft FixIt 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:
