Those are one-day landing websites where users are offered to download the free program, so-called bait e-mails and hacktools. Bait e-mails are a relatively new tactic in malware spreading – you receive the email that mimics some regular notifications about deliveries or bank service conditions changes. Within the e-mail, there is a malicious MS Office file, or a web link which opens the exploit landing site.

Malicious email spam

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

Avoiding it looks quite simple, however, still needs a lot of awareness. Malware can hide in various places, and it is much better to stop it even before it goes into your PC than to rely on an anti-malware program. Simple cybersecurity knowledge is just an important item in the modern world, even if your interaction with a computer stays on YouTube videos. That can save you a lot of money and time which you would spend while looking for a fix guide.
