BugWare ransomware removal instructions
What is BugWare?
BugWare is a ransomware-type virus discovered by MalwareHunterTeam. Once infiltrated, BugWare encrypts stored data using AES-256 cryptography. During encryption, BugWare appends file names with an extension (depending on the BugWare variant): ".[SLAVIC@SECMAIL.PRO].BUGWARE" (first variant), ".[SLAVIC@SECMAIL.PRO].CRIPTOGRAFADO" (second variant) or ".[MAXVISION@SECMAIL.PRO].CRIPTOGRAFADO" (third variant). Following successful encryption, BugWare opens a pop-up window (containing a ransom-demand message) and creates an image file ("wpp.bmp"), placing it on the desktop and also setting it as the desktop wallpaper.
BugWare is Brazilian-based ransomware. The ransom-demand message is in Portuguese and states that files are encrypted using AES cryptography. This encryption algorithm is symmetric and, thus, a single key (used to encrypt and decrypt data) is generated uniquely for each victim. Despite this, the message also states that the generated key is also encrypted using RSA-2048 - an asymmetric encryption algorithm (in which the encryption and decryption keys are different). Criminals store these keys on a remote server. To receive them and restore encrypted data, victims are encouraged to pay a ransom of the equivalent of 1000 Brazilian Real (~$315) in Bitcoins. It is also stated that payment must be submitted within the given time frame (a pop-up contains a countdown timer). The first BugWare variant gives 72 hours, and the second, 168 hours. If the ransom is not paid within one of these time frames, files are (supposedly) deleted permanently. Bear in mind, however, that cyber criminals cannot be trusted. Research shows that these people often ignore victims once payments are submitted. Therefore, there is a high probability that paying will not deliver any positive result (and you will be scammed). Paying is equivalent to sending money to cyber criminals - you will support their malicious businesses. Therefore, we strongly advise you to ignore all requests to contact these people or pay any ransom. Unfortunately, there are no tools capable of cracking the aforementioned encryption algorithms and restoring files compromised by BugWare. The only solution is to restore your files/system from a backup.

BugWare is virtually identical to BTCWare PayDay, ANONCRACK, Asasin, and dozens of other ransomware-type viruses. Although these viruses are designed by different cyber criminals, they have identical behavior - they encrypt files and make ransom demands. The only major differences between ransomware-type viruses are size of ransom (which usually fluctuates between $500 and $1500) and type of encryption algorithm used. Research shows that, unfortunately, most ransomware employs algorithms that generate unique decryption keys. Therefore, unless the malware is not fully developed or has certain bugs/flaws (for example, stores keys locally), file decryption without involvement of developers is impossible (contacting these people is not recommended). For these reasons, ransomware-type viruses such as BugWare present a strong case for maintaining regular data backups.
How did ransomware infect my computer?
How to protect yourself from ransomware infections?
The main reasons for computer infections are lack of knowledge and careless behavior. Be very cautious when browsing the Internet. Never open files attached to emails and received from suspicious addresses - these emails should be deleted without reading. Furthermore, download your software from official sources only and, preferably, using a direct download URL (third party download/installation tools often stealthily install malicious apps). Keep installed software updated and use a legitimate anti-virus/anti-spyware suite. Bear in mind, however, that criminals proliferate ransomware via fake updaters. Therefore, updating software via third party tools is very risky. The key to computer safety is caution.

Instant automatic removal of BugWare virus:
Manual threat removal might be a lengthy and complicated process that requires advanced computer skills. Spyhunter is a professional automatic malware removal tool that is recommended to get rid of BugWare virus. Download it by clicking the button below:
- What is BugWare?
- STEP 1. BugWare virus removal using safe mode with networking.
- STEP 2. BugWare ransomware removal using System Restore.
Windows XP and Windows 7 users: Start your computer in Safe Mode. Click Start, click Shut Down, click Restart, click OK. During your computer start process, press the F8 key on your keyboard multiple times until you see the Windows Advanced Option menu, and then select Safe Mode with Networking from the list.

Windows 8 users: Start Windows 8 is Safe Mode with Networking - Go to Windows 8 Start Screen, type Advanced, in the search results select Settings. Click Advanced startup options, in the opened "General PC Settings" window, select Advanced startup. Click the "Restart now" button. Your computer will now restart into the "Advanced Startup options menu". Click the "Troubleshoot" button, and then click the "Advanced options" button. In the advanced option screen, click "Startup settings". Click the "Restart" button. Your PC will restart into the Startup Settings screen. Press F5 to boot in Safe Mode with Networking.

Windows 10 users: Click the Windows logo and select the Power icon. In the opened menu click "Restart" while holding "Shift" button on your keyboard. In the "choose an option" window click on the "Troubleshoot", next select "Advanced options". In the advanced options menu select "Startup Settings" and click on the "Restart" button. In the following window you should click the "F5" button on your keyboard. This will restart your operating system in safe mode with networking.

Log in to the account infected with the BugWare virus. Start your Internet browser and download a legitimate anti-spyware program. Update the anti-spyware software and start a full system scan. Remove all entries detected.
If you cannot start your computer in Safe Mode with Networking, try performing a System Restore.

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.
2. When Command Prompt mode loads, enter the following line: cd restore and press ENTER.
3. Next, type this line: rstrui.exe and press ENTER.
4. In the opened window, click "Next".
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 BugWare ransomware virus infiltrating your PC).
6. In the opened window, click "Yes".
7. After restoring your computer to a previous date, download and scan your PC with recommended malware removal software to eliminate any remaining BugWare 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 BugWare 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.
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 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 BugWare ransomware.
HitmanPro.Alert CryptoGuard - detects encryption of files and neutralises any attempts without need for user-intervention:
Malwarebytes Anti-Ransomware Beta uses advanced proactive technology that monitors ransomware activity and terminates it immediately - before reaching users' files:
- The best way to avoid damage from ransomware infections is to maintain regular up-to-date backups. More information on online backup solutions and data recovery software Here.
