Within the e-mail, 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.

Avoiding it looks quite easy, but still requires a lot of awareness.

Simple cybersecurity knowledge is just an essential thing in the modern-day world, even if your interaction with a PC remains on YouTube videos. That may save you a lot of time and money which you would spend while seeking a fixing guide.
