Those are one-day landing sites where victims are offered to download and install the free program, so-called bait emails and hacktools.

Inside of 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 fairly easy, however, still demands tons of awareness. Malware can hide in various places, and it is much better to prevent it even before it gets into your PC than to rely on an anti-malware program. Standard cybersecurity knowledge is just an important thing in the modern world, even if your interaction with a computer remains on YouTube videos. That can save you a great deal of money and time which you would certainly spend while seeking a solution.
