Inside of the e-mail, there is a malicious MS Office file, or a link which leads to the exploit landing site.

Malicious email spam

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

Standard cybersecurity awareness is just an essential thing in the modern world, even if your relationship with a PC stays on YouTube videos. That can save you a lot of money and time which you would spend while trying to find a solution.
