Where did I get the Ransom:MSIL/Filecoder.PKC!MSR?

Routine methods of Ransom:MSIL/Filecoder.PKC!MSR distribution are typical for all other ransomware variants. Those are one-day landing web pages where victims are offered to download the free program, so-called bait emails and hacktools. Bait e-mails are a pretty new tactic in malware distribution – you receive the e-mail that mimics some routine notifications about deliveries or bank service conditions shifts. Inside of the e-mail, there is a malicious 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.

Avoiding it looks fairly easy, however, still requires a lot of attention. Malware can hide in various spots, and it is far better to prevent it even before it goes into your system than to rely on an anti-malware program. Common cybersecurity knowledge is just an important item in the modern world, even if your interaction with a PC remains on YouTube videos. That may save you a lot of time and money which you would spend while trying to find a fixing guide.
