The message freezes web browser’s screen as it lacks “Close” button. Due to this fact and warnings related to system’s security, people often fall for believing that this is a real problem. Despite the lack of a Close button, there is a “Next” button provided. However, it’s crucial NOT to click it because it contains a link to a scammers’ website, which may include installer of the remote desktop tool, such as LogMeIn. As a consequence, online crooks may get remote access to your computer and start sucking up personally-identifiable information. However, usually, the installation of this tool requires user’s permission and, thankfully, people are aware enough of fraudulent activities on the Internet and prevent themselves from installing it without reason. Nevertheless, clicking the “Next” button on “Critical System Failure” support scam alert is not the primary purpose.

That’s why the content of the message is a serious system infection and a necessity of professional support. 855-616-6772 is the number that supposedly belongs to professional IT technicians. However, that’s just what crooks are saying. The people sitting on the other side of the handset are frauds who may try to shove you a fictitious service for a considerable sum of money. They may also ask people to install remote desktop tools and doing so would be the biggest mistake ever. In a nutshell, “Critical System Failure” tech support has nothing to do with the actual performance of your PC. It’s a hoax, which pollutes your web browser, takes up CPU, and may open security loopholes. Therefore, it’s crucial to fix “Critical System Failure” error ASAP.
