To hack it with a brute force, you need a lot more time than our galaxy currently exists, and possibly will exist.

Thus, seeing the MSIL/Injector.VYF detection is a clear signal that you must begin the elimination procedure.

Where did I get the MSIL/Injector.VYF?

Routine tactics of MSIL/Injector.VYF distribution are usual for all other ransomware variants. Those are one-day landing sites where users are offered to download and install the free software, so-called bait e-mails and hacktools. Bait e-mails are a quite new tactic in malware spreading – you get the e-mail that mimics some standard notifications about shippings or bank service conditions updates. Within the e-mail, there is a malicious MS Office file, or a link which opens the exploit landing site.

Malicious email spam

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

Preventing it looks fairly uncomplicated, but still needs a lot of attention. Malware can hide in different spots, and it is far better to stop it even before it goes into your computer than to rely on an anti-malware program. Simple cybersecurity awareness is just an essential item in the modern-day world, even if your relationship with a computer stays on YouTube videos. That may save you a lot of time and money which you would spend while searching for a fix guide.
