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

Within the email, there is a corrupted MS Office file, or a link which leads to the exploit landing site.

Malicious email spam

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

Preventing it looks fairly easy, but still needs a lot of focus. Malware can hide in various places, and it is far better to prevent it even before it invades your system than to rely upon an anti-malware program. Basic cybersecurity awareness is just an essential item in the modern world, even if your relationship with a PC stays on YouTube videos. That can save you a lot of time and money which you would certainly spend while seeking a fixing guide.
