Ransomware has actually been a headache for the last 4 years. It is challenging to realize a more dangerous malware for both individual users and organizations. The algorithms utilized in Ransom:Win32/StopCrypt.PMA!MTB (usually, RHA-1028 or AES-256) are not hackable – with minor exclusions. To hack it with a brute force, you need to have more time than our galaxy actually exists, and possibly will exist. But that virus does not do all these horrible things instantly – it can take up to a few hours to cipher all of your files. Thus, seeing the Ransom:Win32/StopCrypt.PMA!MTB detection is a clear signal that you have to start the clearing process.

Where did I get the Ransom:Win32/StopCrypt.PMA!MTB?

Common tactics of Ransom:Win32/StopCrypt.PMA!MTB distribution are basic for all other ransomware examples. Those are one-day landing sites where users are offered to download the free program, so-called bait e-mails and hacktools. Bait emails are a relatively modern strategy in malware spreading – you receive the email that simulates some routine notifications about shipments or bank service conditions changes. Within the email, there is a corrupted MS Office file, or a 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 quite easy, however, still needs a lot of attention. Malware can hide in different spots, and it is much better to prevent it even before it gets into your PC than to rely upon an anti-malware program. Common cybersecurity awareness is just an important item in the modern world, even if your interaction with a PC remains on YouTube videos. That can keep you a great deal of time and money which you would spend while seeking a fixing guide.
