Where did I get the Ransom.FileCryptor.OL?

Usual tactics of Ransom.FileCryptor.OL injection are usual for all other ransomware examples. Those are one-day landing websites where users are offered to download and install the free program, so-called bait e-mails and hacktools. Bait emails are a pretty modern method in malware distribution – you get the e-mail that mimics some standard notifications about deliveries or bank service conditions modifications. Within the e-mail, 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.

Avoiding it looks pretty easy, but still requires a lot of focus. Malware can hide in various spots, and it is far better to prevent it even before it goes into your computer than to depend on an anti-malware program. Common cybersecurity awareness is just an important thing in the modern world, even if your interaction with a PC remains on YouTube videos. That may keep you a lot of money and time which you would spend while seeking a fix guide.
