It could be that users carelessly install Sweep Clean PC Pro and 1-888-243-3533 Support with freeware. According to our researchers, the malware could be spread with bundled applications that are promoted on questionable file-sharing web pages. Often users simply click the “next” button and do not read the terms and conditions presented in the installation wizard. Unfortunately, by doing so, they miss the chance to prevent suspicious applications from entering their system. When it comes to freeware, it is best to make sure that it is not harmful and download it from reliable web pages.

The software creates a folder named as Sweep Clean PC Pro in the C:\Program Files (x86) or C:\Program Files folder. Then it modifies Shell Value name located in the HKLM\SOFTWARE\Wow6432Node\Microsoft\Windows NT\CurrentVersion\Winlogon and HKCU\Software\Microsoft\Windows NT\CurrentVersion\Winlogon directories. It replaces Shell Value data with C:\Program Files (x86)\Sweep Clean PC Pro\black.exe. This change does not allow your system to launch explorer.exe. As a consequence, you lose control over your PC as your desktop is replaced with Sweep Clean PC Pro and 1-888-243-3533 Support black screen.

If you have the malicious program on your system, you should see a black screen that has a CMD button and a fake Product Key verification window. There might be buttons with links to official web pages of TeamViewer, Supremo, Logmein, and Ammyy. Moreover, there should be a pop-up that says “Your Windows (Microsoft) Computer has been blocked. Windows System Alart! Call Microsoft at 1-888-243-3533 !” The text says that you are blocked from using the Internet because your passwords and other personal data could be accessed by stalkers, so you need to check your computer. Users who do not understand that this could be a scam might panic and call the fake support number.

It is possible that the people who talk with users might pretend to be members of the Microsoft customer service. Since the pop-up says that your computer must be “inspected before you continue using your Internet,” it could be that the fictitious support members would try to sell useless or overpriced software. The fake Product, Key verification window, might be placed so you would reveal your legitimate key and the malware’s developers could steal it. Since you now understand that this is not an actual Microsoft request, but a fake notification caused by Sweep Clean PC Pro and 1-888-243-3533 Support, you should not hesitate to delete the software from your computer.

The only way to get rid of the black screen is to click the CMD button. This button will launch Command Prompt window that will allow you to open the Task Manager. Once you do that, you should use the Task Manager to kill the malicious process called windowsactivate.exe (32BIT). After that, users need to access the Windows Registry and modify a couple of values that were changed by the malware. Lastly, you should delete Sweep Clean PC Pro from the Program files directory. This might seem complicated, and that is why we recommend users to take a look at the step by step removal instructions below the article.
