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

Malicious email spam

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

Simple cybersecurity awareness is just an important thing in the modern-day world, even if your relationship with a PC remains on YouTube videos. That may save you a lot of time and money which you would certainly spend while searching for a fix guide.
