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

Within the email, there is a malicious MS Office file, or a link which opens the exploit landing page.

Malicious email spam

That can save you a lot of time and money which you would spend while trying to find a solution.
