BTCWare ransomware removal instructions

What is BTCWare?

Discovered by malware researcher, MalwareHunterTeam, BTCWare is an updated version of a ransomware-type virus called Crptxxx. This ransomware is distributed via a malicious application called "Rogers Hi-Speed Internet". Once infiltrated, BTCWare encrypts files and appends filenames with the ".btcware" extension (e.g., "sample.jpg" is renamed to "sample.jpg.btcware"). BTCWare then creates an HTM file ("#_HOW_TO_FIX_!.hta.htm"), placing it on the desktop.
BTCWare's HTM file contains a short message that encourages users to visit a Tor website. After opening the website, victims are encouraged to pay a ransom of .5 Bitcoin (currently, .5 BTC is equivalent to approximately $490) to restore the files. Unfortunately, no additional information is provided. It is currently unknown whether BTCWare uses symmetric or asymmetric cryptography, however, decryption without a unique key is impossible. Cyber criminals store this key on a remote server and victims are encouraged to pay to receive it. In fact, paying does not guarantee that your files will ever be decrypted and cyber criminals often ignore victims once ransoms are paid. There is a high probability that paying will not deliver any positive result  and you might be scammed. Never attempt to contact these people or pay any ransom. Unfortunately, there are no tools capable of restoring files encrypted by BTCWare. Therefore, the only solution is to restore files/system from a backup.

There are dozens of ransomware-type viruses similar to BTCWare including AngleWareZorro, and Flotera - these are just some examples from many. All of these viruses encrypt files and make ransom demands. The only major differences are size of ransom and type of encryption algorithm (symmetric/asymmetric) used. Cyber criminals often proliferate this kind of malware by employing fake software updaters, trojans, peer-to-peer (P2P) networks (such as torrents, eMule, etc.), third party software download sources (freeware download/free file hosting websites, etc.), and spam emails (malicious attachments). Therefore, keep your installed applications up-to-date and use a legitimate anti-virus/anti-spyware suite. Bear in mind, however, that criminals often use fake updaters to proliferate viruses. Therefore, updating installed apps via third party tools is not recommended. Furthermore, never download software from unofficial sources or open files received from suspicious emails. The key to computer safety is caution.

1. During your computer start process, press the F8 key on your keyboard multiple times until the Windows Advanced Options menu appears, and then select Safe Mode with Command Prompt from the list and press ENTER.
Boot your computer in Safe Mode with Command Prompt
2. When Command Prompt mode loads, enter the following line: cd restore and press ENTER.

4. In the opened window, click "Next".
restore system files and settings
5. Select one of the available Restore Points and click "Next" (this will restore your computer system to an earlier time and date, prior to the BTCWare ransomware virus infiltrating your PC).
select a restore point
6. In the opened window, click "Yes".
run system restore
7. After restoring your computer to a previous date, download and scan your PC with recommended malware removal software to eliminate any remaining BTCWare ransomware files.
To restore individual files encrypted by this ransomware, try using Windows Previous Versions feature. This method is only effective if the System Restore function was enabled on an infected operating system. Note that some variants of BTCWare are known to remove Shadow Volume Copies of the files, so this method may not work on all computers.
To restore a file, right-click over it, go into Properties, and select the Previous Versions tab. If the relevant file has a Restore Point, select it and click the "Restore" button.
Restoring files encrypted by CryptoDefense
If you cannot start your computer in Safe Mode with Networking (or with Command Prompt), boot your computer using a rescue disk. Some variants of ransomware disable Safe Mode making its removal complicated. For this step, you require access to another computer.
To regain control of the files encrypted by BTCWare, you can also try using a program called Shadow Explorer. More information on how to use this program is available here.

To protect your computer from file encryption ransomware such as this, use reputable antivirus and anti-spyware programs. As an extra protection method, you can use programs called HitmanPro.Alert and EasySync CryptoMonitor, which artificially implant group policy objects into the registry to block rogue programs such as BTCWare ransomware.
HitmanPro.Alert CryptoGuard - detects encryption of files and neutralises any attempts without need for user-intervention:
