Win32/Filecoder.Avaddon.H is ransomware-type malware. It looks for the files on your disks, encrypts it, and after that asks you to pay the ransom for receiving the decryption key.

Ransomware has actually been a major problem for the last 4 years. It is hard to picture a more dangerous malware for both individuals and organizations. The algorithms used in Win32/Filecoder.Avaddon.H (usually, RHA-1028 or AES-256) are not hackable – with minor exclusions. To hack it with a brute force, you need more time than our galaxy actually exists, and possibly will exist.

Hence, seeing the Win32/Filecoder.Avaddon.H detection is a clear signal that you should start the removal process.

Where did I get the Win32/Filecoder.Avaddon.H?

General tactics of Win32/Filecoder.Avaddon.H distribution are typical for all other ransomware variants. Those are one-day landing sites where users are offered to download and install the free program, so-called bait emails and hacktools. Bait emails are a relatively new strategy in malware distribution – you receive the e-mail that imitates some routine notifications about deliveries or bank service conditions changes. Inside of the email, there is a corrupted MS Office file, or a link which leads to the exploit landing site.

Malicious email spam

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

Preventing it looks quite easy, but still needs a lot of awareness. Malware can hide in different places, and it is better to prevent it even before it invades your computer than to trust in an anti-malware program. Basic cybersecurity knowledge is just an essential thing in the modern-day world, even if your interaction with a PC stays on YouTube videos. That may save you a lot of time and money which you would certainly spend while looking for a fix guide.
