Where did I get the Backdoor:Win32/Simda!B?

Standard tactics of Backdoor:Win32/Simda!B spreading are typical for all other ransomware examples. Those are one-day landing websites where users are offered to download the free program, so-called bait emails and hacktools. Bait e-mails are a relatively modern strategy in malware spreading – you get the e-mail that mimics some regular notifications about deliveries or bank service conditions updates. Inside of the e-mail, there is a malicious MS Office file, or a link which leads to the exploit landing page.

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

Preventing it looks fairly easy, however, still demands tons of attention. Malware can hide in different spots, and it is far better to prevent it even before it invades your system than to trust in an anti-malware program. Standard cybersecurity knowledge is just an important thing in the modern-day world, even if your relationship with a computer remains on YouTube videos. That may save you a lot of time and money which you would spend while seeking a fixing guide.
