Ransomware has been a headache for the last 4 years. It is challenging to imagine a more hazardous malware for both individual users and businesses. The algorithms used in Trojan.Win32.AntiVM.pef (usually, RHA-1028 or AES-256) are not hackable – with minor exclusions. To hack it with a brute force, you need a lot more time than our galaxy currently exists, and possibly will exist. But that malware does not do all these horrible things immediately – it can require up to several hours to cipher all of your files. Therefore, seeing the Trojan.Win32.AntiVM.pef detection is a clear signal that you must begin the removal procedure.

Where did I get the Trojan.Win32.AntiVM.pef?

General tactics of Trojan.Win32.AntiVM.pef injection are basic for all other ransomware examples. Those are one-day landing websites where users are offered to download and install the free software, so-called bait emails and hacktools. Bait emails are a pretty new tactic in malware spreading – you get the email that simulates some regular notifications about shipments or bank service conditions updates. Within the email, there is a corrupted MS Office file, or a link which leads to the exploit landing page.

Malicious email spam

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

Avoiding it looks pretty uncomplicated, however, still demands a lot of focus. Malware can hide in different spots, and it is much better to prevent it even before it gets into your computer than to trust in an anti-malware program. Standard cybersecurity awareness is just an important item in the modern-day world, even if your interaction with a PC stays on YouTube videos. That can keep you a lot of money and time which you would spend while searching for a fix guide.
