Where did I get the Trojan:MSIL/Polyransom!atmn?

Those are one-day landing websites where victims are offered to download and install the free program, so-called bait emails and hacktools. Bait emails are a quite new method in malware spreading – you receive the email that mimics some routine notifications about shipments or bank service conditions changes. Within the e-mail, there is a corrupted MS Office file, or a web link which opens the exploit landing page.

Malicious email spam

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

Avoiding it looks pretty simple, but still demands tons of recognition. Malware can hide in various places, and it is far better to stop it even before it goes into your system than to rely upon an anti-malware program. Simple 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 solution.
