It comes from a software company I've never heard of before.
Somehow, the software has already scanned your device and detected all these viruses.
And it will take more than luck to close the popup, because the close button (x) is either hidden, or hovering over it causes a new window to open over the previous one.
You “must” act fast! It usually has a big red button (sometimes it even flashes, just in case you don’t see it right away), telling you that you can “Download Now!”
The pop-up title will always be something like “Warning!” or “Virus list of bahrain whatsapp phone numbers Detected!”
How to avoid scareware?
Knowing how to identify scareware is the first step to avoiding it. Here are some additional tips:
1. Don't react immediately to the pop-up
Attackers are trying to take advantage of your emotions and use intimidation tactics to force you into making a hasty decision. They also do this in another type of social engineering attack, called “ whaling .” Don’t react immediately. Instead, take a deep breath and relax.
2. Think rationally
Read between the lines. There is more to that “warning” than meets the eye.
For example, have you heard of this software before? Know that legitimate companies, such as Norton, Kaspersky and others would NEVER do something like this.
On the other hand, how could they possibly have scanned your device and detected these viruses if you have never interacted with them or their software?
Typically, you need to download antivirus software to your device and tell it to scan for malware. But even then, a virus scan can take anywhere from minutes (for a quick scan) to hours (for a deep scan).
