What is Alvin ransomware?

Alvin ransomware – new type of DMR malware that will lock your files

Alvin ransomwareAlvin ransomware is a file locking virus that stems from DMR malware family

Alvin ransomware is a cryptovirus that encrypts all non-system computer data and demands a ransom for decoding it. It's a new type of DMR malware. The whole encryption is done using AES[1] algorithms. Victims' infected files gain an extension .ALVIN, hence the name of the virus.

After the dirty deed is done, users notice a new file – “HOW TO RECOVER ENCRYPTED FILES.txt” where the cybercriminals urge the victims to contact them via email – or (the latter should be used if the perpetrators don't respond within 24 hours). As a ransom, the victims would have to pay an unspecified amount of Bitcoins.

NAME ALVIN ransomware, Alvin file virus
TYPE Ransomware, cryptovirus, malware
RANSOM NOTE Demands, instructions, and contact information is provided in a newly created file HOW TO RECOVER ENCRYPTED FILES.txt
RANSOM AMOUNT The amount is not specified, but they demand Bitcoin cryptocurrency as ransom
CONTACT EMAIL Two emails are provided – or Second one should only be used if the perps don't respond within 24 hours to a letter sent to the first given email.
DISTRIBUTION Spam emails, infectious hyperlinks, software “cracks”
REMOVAL Victims shouldn't try and remove virus manually. Let the professionals do the dirty work – use anti-malware software, such as SpyHunter 5Combo Cleaner or Malwarebytes, to automatically remove ALVIN virus
SYSTEM FIX This malware might have altered your computers' system files, if you experience lag, crashes, or any other abnormal behaviour use FortectIntego to restore your system

As a sign of good faith, the cybercriminals offer the victim to test their decoding tool by sending one file (not larger than 1MB) for a free decryption, thus proving that the alleged decoding tool exists. The perpetrators also threaten that they will keep your decryption code only for a week.

In no way does that mean that after contacting the developers of ALVIN virus and meeting their ransom demands, the user will ever get the tool to decode his encrypted data. In most cases, users not only don't get what was promised but instead, some more malware is installed on their device so that the crooks could get even more out of their victims. We strongly recommend to never give in to the ransom demands.

The whole ransom note reads as follows:

"ALVIN RANSOMWARE"   Your unique ID:"54F49153"
All personal files on your computer are encrypted!
Before you make a payment you should test our tool first for decrypting your data.
Before paying to send us up to 1 file for free decryption.
The total size of the file must be less than 1Mb (the file should not be important to you).
Don't worry, you can restore all your files.
Without the original key recovery is impossible.
If you want to decrypt your files, you have to pay in Bitcoin.
The price depends on how fast you write to us.
If you want to restore files, write us to the e-mail: ""

We don't give guarantees that full recovery is possible. 
2-Please do not change the name of files or file extension if your files are important to you!

The ALVIN virus might do some more damage, apart from encrypting your data. If it's anything like his big brother DMR ransomware, it will alter Windows host files preventing the victims from visiting security-related sites and networks and finding out alternate data recovery solutions.

Alvin ransomware virusAlvin ransomware is a type of virus that holds file hostage until ransom is paid to the attackers

That said, users should remove ALVIN virus right after its detection before it has done more harm. Trustworthy and reliable anti-malware software is a must nowadays. If you're undecided, we recommend using SpyHunter 5Combo Cleaner or Malwarebytes to completely remove the virus and all its allocated files.

Unfortunately, ALVIN ransomware removal won't decrypt your data, but it will prevent your incoming files from being encrypted in the future. However, corrupted, altered Windows files might keep you from using your computer properly, even after the deletion of the virus. To fix the registry and other locations the virus might have got his dirty hands-on, we recommend using FortectIntego, as this tool might restore your computer so you could use it as if nothing ever happened.

Methods of malware/ransomware distribution

The most common way the ALVIN virus and other malware spreads, according to,[2] is via email spam.[3] Users usually receive legitimately looking emails that appear to come from their employers, banks, etc. Attached to these emails are malicious files that, right after opening/downloading, start the infection.

Internet users should always be aware of what they're opening, what they're clicking on because the web is full of traps. Never open emails that look fishy, never open any email attachments without scanning them first with anti-malware software.

Malware is also distributed via torrent sites, such as BitTorrent, The Pirate Bay, etc., whilst downloading game cheat codes, illegal activation tools (aka “cracks”). To evade becoming victims, users should download their desired apps only from the developers.

To ensure systems' safety, users should acquire dependable anti-malware software that would keep them safe while browsing.

This method only works if you had System Restore point setup (which was not deleted by malware).

  • Find an encrypted file you need to restore and right-click on it;
  • Select “Properties” and go to “Previous versions” tab;
  • Here, check each of available copies of the file in “Folder versions”. You should select the version you want to recover and click “Restore”.

How to prevent from getting ransomware

Do not let government spy on you

The government has many issues in regards to tracking users' data and spying on citizens, so you should take this into consideration and learn more about shady information gathering practices. Avoid any unwanted government tracking or spying by going totally anonymous on the internet. 

You can choose a different location when you go online and access any material you want without particular content restrictions. You can easily enjoy internet connection without any risks of being hacked by using Private Internet Access VPN.

Control the information that can be accessed by government any other unwanted party and surf online without being spied on. Even if you are not involved in illegal activities or trust your selection of services, platforms, be suspicious for your own security and take precautionary measures by using the VPN service.

Backup files for the later use, in case of the malware attack

Computer users can suffer from data losses due to cyber infections or their own faulty doings. Ransomware can encrypt and hold files hostage, while unforeseen power cuts might cause a loss of important documents. If you have proper up-to-date backups, you can easily recover after such an incident and get back to work. It is also equally important to update backups on a regular basis so that the newest information remains intact – you can set this process to be performed automatically.

When you have the previous version of every important document or project you can avoid frustration and breakdowns. It comes in handy when malware strikes out of nowhere. Use Data Recovery Pro for the data restoration process.
