Bait emails are a quite modern method in malware distribution – you get the email that mimics some routine notifications about deliveries or bank service conditions modifications. Inside of the email, there is an infected 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 pretty simple, but still demands a lot of awareness. Malware can hide in different places, and it is much better to prevent it even before it gets into your computer than to trust in an anti-malware program. Common cybersecurity knowledge is just an essential item in the modern-day world, even if your relationship with a computer stays on YouTube videos. That can save you a great deal of time and money which you would spend while trying to find a fix guide.
