How did the Gapo ransomware get on my computer?

The Gapo ransomware spreads by placing websites to download hacked programs or games. They keep their eye on all hype themes which can be chosen to spread ransomware. New games releases, new popular films – Gapo developers make everything to get their money on that. Some of the most popular techniques these criminals utilize is one-day websites with torrent downloading links. Nevertheless, following the contemporary news is not the single manner these crooks utilize. Options that have already turned into classic, such as email spamming, are also ordinary for STOP/Djvu ransomware spreading.

Malicious email spam

The example of email spamming that may lead to Gapo ransomware injection

Avoiding this ransomware does not need a lot of initiative. Considering the ordinary rules of PC hygiene will considerably minimize all risks. Bear in mind that opening all files you get on email is not a great option. Even worse case is to allow macros in Microsoft Office documents. But it is better to stop the malware attack 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, and also when you see things like “”– it is likely a genuine email. On the other hand, stuff that tries to resemble Amazon or FedEx shipping notice, but uses the e-mail address of “”– must make you get on the alarm. Above, you can see the example of such a message.

Illegal sources of different digital things require some additional explanation. Breaking copyright law already exposes you to the risk of being fined. Nevertheless, using torrent trackers or third-party sites to download “free” programs also exposes you to a wide range of malware. No one can oversee undisclosed people who start the torrent seeding or release the hacked program version on the site with pirated program.
