This is now actually scary, but as previously stated, mildly annoying. This is where you get bombarded with pop-up messaged claiming that malware has been detected. They will claim the only way to clear this malware is to pay the ransom. Realistically the files are harmless, they won’t cause damage to your system, but they will get on your nerves.
What you should know is that a real cybersecurity software program wont solicit their customers. If you don’t already have their software on your computer, they wont me monitoring you for any type of infections. If you do have do have security software, why would they charge you more after you’ve already paid them for protection? The purpose of paying for cybersecurity protection is not to just be notified you’re infected, its to actually protect you when you do become infected.
