Where did I get the Win32/Filecoder.Buran.K?

Those are one-day landing sites where users are offered to download the free program, so-called bait emails and hacktools. Bait emails are a relatively new method in malware distribution – you get the email that mimics some normal notifications about shipments or bank service conditions shifts. Inside of 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, but still demands a lot of focus. Malware can hide in different spots, and it is much better to stop it even before it gets into your system than to trust in an anti-malware program. Standard cybersecurity knowledge is just an essential thing in the modern world, even if your relationship with a PC remains on YouTube videos. That may save you a lot of money and time which you would spend while seeking a solution.
