How did the Efvc ransomware get on my computer?

The Efvc ransomware spreads by placing websites to get hacked programs or games. Cybercriminals that distribute this ransomware are extremely tricky, and aim to keep in touch with the latest things. New games introductions, new popular movies – Efvc creators make whatever to get their money on that. One of the most popular techniques these crooks apply is one-day websites with torrent downloading links. Nonetheless, following the current news is not the only manner these criminals utilize. Options that have already become classic, such as e-mail spamming, are likewise standard for STOP/Djvu ransomware spreading.

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

Avoiding this ransomware does not need a lot of effort. Considering the standard rules of computer hygiene will significantly minimize all hazards. Bear in mind that starting all files you get on e-mail is not a great idea. Even worse case is to enable macros in Microsoft Office documents. However, it is much better to avoid the malware intrusion at the moment when you have only opened the email message. Inspecting the sender’s address can point out a lot about what you can expect, as well as when you see things like “support@amazon.com”– it is likely a genuine e-mail. At the same time, stuff that tries to resemble Amazon or FedEx shipment alert, however, uses the email address of “amazonspurrot1363@gmail.com”– must make you be on the alarm. Above, you can see the example of such a message.

Illegal sources of various digital things require some extra description. Going against copyright policy already throws you to the risk of being fined. However, using torrent trackers or third-party websites to download “free” programs also exposes you to a wide range of malware. Nobody can oversee undisclosed people who launch the torrent seeding or release the hacked program version on the site with pirated software.
