The false message “informs” the victim that the computer has been blocked because “Windows has detected some suspicious activity from your IP address.” The alert falsely claims that virus or spyware has caused a security breach at victim’s network location, which is absolute nonsense.

Traditionally, the alert urges the victim to call a number provided in order to get help from “engineers” that ostensibly can walk the victim through the malware removal process via phone. If you're looking for honest malware removal guides, we invite you to visit sites such as DieViren[3] instead.

How to prevent from getting “CRITICAL ALERT FROM WINDOWS” fake pop-up

Stream videos without limitations, no matter where you are

There are multiple parties that could find out almost anything about you by checking your online activity. While this is highly unlikely, advertisers and tech companies are constantly tracking you online. The first step to privacy should be a secure browser that focuses on tracker reduction to a minimum.

Even if you employ a secure browser, you will not be able to access websites that are restricted due to local government laws or other reasons. In other words, you may not be able to stream Disney+ or US-based Netflix in some countries. To bypass these restrictions, you can employ a powerful Private Internet Access VPN, which provides dedicated servers for torrenting and streaming, not slowing you down in the process.

Data backups are important – recover your lost files

Ransomware is one of the biggest threats to personal data. Once it is executed on a machine, it launches a sophisticated encryption algorithm that locks all your files, although it does not destroy them. The most common misconception is that anti-malware software can return files to their previous states. This is not true, however, and data remains locked after the malicious payload is deleted.

While regular data backups are the only secure method to recover your files after a ransomware attack, tools such as Data Recovery Pro can also be effective and restore at least some of your lost data.
