This page aims to help you remove .Micro File Virus. These .Micro File Virus removal instructions work for all versions of Windows.

Important information. Read before doing anything else.

The .Micro File Virus is a computer virus of the very dangerous Ransomware variety. It can also be encountered as “fichier .micro” as evidenced by our readers. This particular strain of ransomware has hit Italy pretty hard and chances are that our Italian readers are looking for a way to decriptare file .micro.

.Micro File is actually a successor of the TeslaCrypt 3.0 ransomware virus. The name of the virus is drawn from the text file it uses to deliver the ransomware note – a file that actually ends with the .micro extension. It is easily recognizable – your files can’t be opened or accessed in any other way, they have a strange file extension and you have a note on your desktop explaining the details of your dire situation.

We believe it is important to fully understand exactly what you will be facing, how it operates and how you were infected in the first place. You’ll need this knowledge before even trying to remove .Micro File Virus or “fichier .micro” and restore your files. So be patient and read this article carefully.

The first and most important thing to do is to remain calm – if your files have already been encrypted and the file .micro has revealed itself, then it is already too late for quick and decisive action. TeslaCrypt 3.0, on which .Micro file is built upon, is a ransomware with fearsome reputation. So far no known method exists to decrypt the files targeted by the virus, but they are alternative methods that can recover them. We’ll provide you with more details later in the article.

  • WARNING! Formatting your hard drive and reinstalling windows are excellent methods to surely get rid of some really nasty viruses, but they will not get your files back – in fact these actions will make it even worse to recover them. Attempt them only if you really don’t need the files that were encrypted by the virus.

This is how .Micro File Virus works

Once .Micro File Virus aka fichier .micro have accessed your computer (for how that may have happened you can read below), it will start compiling a list of your most often used personal files. Note that no system files will be targeted. When the list’s done the encryption process begins and very soon your files will be encrypted and replaced by unreadable and inaccessible copies. Once that happens you are left with limited options. You can follow the instructions contained in the note and pay the ransom in the hope that you will receive a decryption key. We strongly advise against doing that. We will explain why in the sections below. Another possibility is to wait and hope that someone in the online community will eventually crack the encryption. You are entirely at the mercy of other people and no one really knows if this will ever happen. The third option is to try and get things back under your control and try the method we will describe. While we can’t guarantee success, at least you will not have done anything to worsen your situation.

  • A work of caution – there are circulating some programs that claim to be able to decrypt the .Micro virus encrypted files and even files affected by other ransomware. Do not fall for this nasty scam – it was created by online vultures who prey on the misfortune of people who had become victims of this ransomware. Of course, it is always possible that someone really did make a breakthrough and figured out a way to reverse the virus. If you believe this may be the case try to ask for proof before paying any money for such a software – preferably send one of your encrypted files to get restored.

To pay or not to pay?

This is not a simple question to answer and frankly no one can answer it for you. We can only provide our point of view and let you decide – you should not pay the ransom in almost any case. We leave the odd 1% for some really strange scenarios. But in the other 99% you should definitely exhaust completely all other options and then some. There are two major reasons why you should be taking this approach in our honest opinion:

  • You will be trying to conduct a business transaction of sorts with cyber criminals. Let’s not try to sugarcoat this – there are absolutely no guarantees or even reasons to believe that you will receive a decryption key once you send the ransom payment. You will be relying on some blind hope that the criminals who have resorted to extortion will keep their “word” and you will get your files back. But just as likely outcome unfortunately would be that you are left with nothing but additional ransom demands.
  • Another thing to consider – the Ransomware extortion has rapidly turned into a massive industry. The hackers or criminals are making millions of dollars. They have absolutely no intention or incentive to stop doing what they are doing since it’s a massive revenue stream. The only way for that to change? Stop paying them for something that is rightfully yours. The first step in the fight against Ransomware is to hamper the criminals’ income source.

How were your defenses breached?

Almost always Ransomware applications find their way to the victims’ systems by way of using other malware as a “backdoor”. In most cases the culprit is some form of a Trojan horse malware. In fact we advise you to thoroughly check your system for a possible Trojan infection (in addition to the Ransomware), but only after you’ve dealt with the bigger threat that is .Micro File Virus, also known as “fichier .micro”. Now, it is possible that this information may raise even more questions, like “how did I end up with a Trojan virus then?” for example. We will try to answer that one as well.

  • The oldest and still widely used method for malware spreading – email attachments. You have probably heard of this one, yet here are some pointers for you. Always be wary when opening files attached to e-mails, even if they have been sent to you from seemingly reputable companies and organizations. Phishing e-mail are a popular practice, so you can’t let your guard down. Perform the necessary checks and scans before opening any downloaded attachment.
  • Compromised executable files (.exe) downloaded from torrent or file-sharing websites. There’s questionable control over what gets uploaded and by whom at such sites, so if you are using any form of p2p you should definitely scan all files before executing them, especially if they end with an .exe extension.
  • If you are missing a certain .DLL file, or you’re looking to fix a particular system error, look for a solution online. But never download such files from the internet – you are just inviting trouble and almost in all cases you end up with a Trojan horse or worse.
