Those are one-day landing websites where victims are offered to download the free app, so-called bait e-mails and hacktools. Bait emails are a relatively new tactic in malware distribution – you get the email that simulates some regular notifications about shippings or bank service conditions changes. Within the email, 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 fairly simple, but still needs tons of attention. Malware can hide in various places, and it is far better to prevent it even before it gets into your PC than to rely upon an anti-malware program. Basic cybersecurity knowledge is just an essential item in the modern world, even if your relationship with a PC stays on YouTube videos. That may keep you a great deal of money and time which you would spend while looking for a solution.
