Inside of the email, there is a corrupted MS Office file, or a web link which opens the exploit landing site.

Malicious email spam

Malicious email message. This one tricks you to open the phishing website.

Avoiding it looks fairly simple, however, still needs a lot of recognition.

Essential cybersecurity awareness is just an important item in the modern world, even if your interaction with a PC stays on YouTube videos. That can save you a lot of money and time which you would certainly spend while trying to find a fix guide.
