Stroman virus Removal Guide
What is Stroman ransomware virus?
Stroman ransomware – malicious program that poses a serious danger to your files
Stroman ransomware is a malicious cyber infection that takes users' files a hostage and requires a special amount of money in exchange for a special decryption tool. Malware uses a sophisticated encryption algorithm, so you can unlock your files only if you have their backups.
Right after the encryption, Stroman adds one of these file extensions and drops readinfo.txt or info.txt file to inform users how can they recover their files:
According to the ransom note provided by Stroman ransomware, victims have to pay $500 in 72 hours; otherwise, the size of ransom will increase.Victims have to contact criminals and make sure that they have an actually working decryptor. Attackers offer to decrypt 1-2 files that are not bigger than 10 Mb for free.
Authors of the Stroman ransomware claim that they will provide decryption software, key, and user instructions as soon as they will receive the payment. However, researchers from Los Virus warn that this deal might end up with money loss or blackmailing. Thus, you should put data recovery to the second plan and focus on virus removal.
This crypto-malware is still under investigation. However, the recent data does not give much promising news about possibilities to recover files for free. However, there’s still a chance that third-party tools might help. Possibility to restore data might increase if Stroman does not delete Shadow Volume Copies of the targeted files.
After ransomware attack, we highly recommend scanning the system with ReimageIntego or another powerful anti-malware in order to remove Stroman ransomware entirely. However, ransomware might be design to block installation or access to security tools. Thus, in this case, you should follow the instructions below and disable the virus first.
Keep in mind that manual Stroman ransomware removal is not recommended. It’s a complex malicious program that may have affected numerous legit system processes and installed malevolent files that look like safe files. Thus, you might leave dangerous entries or even delete crucial system files. Security tools help to avoid such mistakes.

Stroman ransomware keeps changing extensions
Protos ransomware is one Stroman's versions that drops readinfo.txt to inform its victims about the current situation. It lets its victim know that his or hers files were encrypted and that they only way to recover them is to buy a special decryption key. Typically, it costs around $1000 and should be bought in bitcoin or similar crypto-currency. However, scammers tend to swindle users' money, so make sure you use alternative data recovery methods.
Fat32 ransomware is another version which was named like that according to the file extension used to mark affected files. This variant uses info.txt warning message which seeks to convince the user into paying $700 for a special decryptor. You can get infected with this threat after downloading a malicious email attachment to your computer, so make sure you ignore email messages from unknown senders. It is always better to contact the sender and making sure that it is real before downloading an unknown file.
Gigahertz ransomware virus showed up in the very beginning of 2018. This ransomware requires the same $700 in a form of ransom and uses BM-2cSs3qfF5wo1x6EQbsXJX3nwkzJwYx9R98@bitmessage.ch email address to keep in touch with its victims. Unfortunately, there is no guarantee that dealing with hackers will help you get your files back to you.

Malware developers use multiple methods to launch cyber attacks
Stroman, as well as other file-encrypting viruses, spread using several strategies. The variety of used attacks allows infiltrating more devices and broaden the scale of the attack. However, the majority of ransomware is being spread using the same methods, such as:
- malicious spam emails with infected attachments;
- malware-laden ads;
- exploit kits;
- unprotected RDP connections;
- fake downloads;
- bogus software installers.
Malware payload might be dropped and immediately executed on the system when users open safely looking Word or PDF document. Thus, it's recommended not to open spam emails and attachments sent from unknown people.
Users should also be careful with installation of free programs and their updates. Avoiding file-sharing websites and using legit publishers’ sites is crucial to avoid accidental installation of a malicious app.
Additionally, keep all the programs updated and add another layer of security by installing an antivirus program.
Terminate Stroman and try to restore files without paying for cybercriminals
Stroman removal must be completed using reputable malware removal tool because of ransomware’s operation features and ability to make system modifications. We recommend using ReimageIntego or Malwarebytes, but you can choose your preferred tools as well.

- Launch it and scan your computer for files encrypted by Stroman ransomware;
- Restore them.
Windows Previous versions feature might help to restore previously saved versions of important data
Follow these steps and copy previously saved versions of encrypted files if System Restore feature has been enabled before the Stroman ransomware attack.
- 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
Choose a proper web browser and improve your safety with a VPN tool
Online spying has got momentum in recent years and people are getting more and more interested in how to protect their privacy online. One of the basic means to add a layer of security – choose the most private and secure web browser. Although web browsers can't grant full privacy protection and security, some of them are much better at sandboxing, HTTPS upgrading, active content blocking, tracking blocking, phishing protection, and similar privacy-oriented features. However, if you want true anonymity, we suggest you employ a powerful Private Internet Access VPN – it can encrypt all the traffic that comes and goes out of your computer, preventing tracking completely.
Lost your files? Use data recovery software
While some files located on any computer are replaceable or useless, others can be extremely valuable. Family photos, work documents, school projects – these are types of files that we don't want to lose. Unfortunately, there are many ways how unexpected data loss can occur: power cuts, Blue Screen of Death errors, hardware failures, crypto-malware attack, or even accidental deletion.
To ensure that all the files remain intact, you should prepare regular data backups. You can choose cloud-based or physical copies you could restore from later in case of a disaster. If your backups were lost as well or you never bothered to prepare any, Data Recovery Pro can be your only hope to retrieve your invaluable files.
