Where did I get the MSIL/Packed.CodeWall.B suspicious?

Ordinary ways of MSIL/Packed.CodeWall.B suspicious spreading are basic for all other ransomware variants. Those are one-day landing web pages where users are offered to download the free software, so-called bait emails and hacktools. Bait emails are a quite new tactic in malware spreading – you receive the e-mail that imitates some normal notifications about shipments or bank service conditions modifications. Within the e-mail, there is an infected MS Office file, or a web 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 quite easy, but still needs a lot of attention. Malware can hide in different spots, and it is better to stop it even before it invades your PC than to depend on an anti-malware program. General cybersecurity knowledge is just an essential item in the modern world, even if your interaction with a computer stays on YouTube videos. That can keep you a great deal of time and money which you would spend while looking for a solution.
