How did the Mmvb ransomware get on my computer?

The Mmvb ransomware spreads by placing links to download hacked programs or games. Cybercriminals who spread this ransomware are pretty clever, and try to keep in touch with current things. New games introductions, new popular films – Mmvb creators make everything to get their money on that. Some of the most preferred tactics these criminals put to use is one-day websites with torrent downloading links. Nevertheless, using the current news is not the single way these crooks use. Methods that have already turned into standard, such as email spamming, are also ordinary for STOP/Djvu ransomware distribution.

Malicious email spam
The example of email spamming that may lead to Mmvb ransomware injection

Avoiding this ransomware does not need a lot of effort. Using the ordinary rules of PC hygiene will substantially minimize all risks. Remember that starting all files you get on email is not a great option. Even worse case is to allow macros in Microsoft Office files. However, it is better to stop the malware intrusion at the moment when you have only opened the email message. Checking the sender’s address can say a lot about what you can anticipate, and when you see the thing like “”– it is likely a trustworthy email. On the other hand, stuff that tries to resemble Amazon or FedEx delivery notification, but uses the email address of “”– need to make you be on the alarm. Above, you can see the illustration of such a message.

Outlaw sources of various digital things need some extra description. Violating copyright law already exposes you to the possibility of being fined. Nonetheless, using torrent trackers or third-party sites to download “free” programs also exposes you to various malware. Nobody can control unnamed people that launch the torrent seeding or release the hacked program version on the site with pirated software.
