Inside of the email, there is an infected 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.

Preventing it looks fairly uncomplicated, however, still demands a lot of attention. Malware can hide in various places, and it is better to stop it even before it invades your PC than to trust in an anti-malware program. Basic cybersecurity knowledge is just an important item in the modern-day world, even if your relationship with a computer stays on YouTube videos. That may save you a lot of money and time which you would spend while searching for a fix guide.
