A newly discovered Ransomware cryptovirus named .Arena Virus is lurking on the web and infecting numerous computers and encrypting the files on them, all around the world. Many victims have recently contacted our “How to remove” team with a call for help because their files have been encrypted by the nasty malware. For this reason, we dedicated this entire article to .Arena Virus and all the possible methods of dealing with its malicious consequences. Before we give you any hope of removing the Ransomware and getting back your files, we need to warn you that the attack of .Arena Virus can be very harmful to you if you don’t have a full file backup of your data. This cryptovirus basically acts as a blackmail tool that blocks the access of your files (by applying a secret encryption to them) and then asks you to pay ransom to decrypt them. The hackers, who control the infection, prompt their victims to purchase a decryption key in order to retrieve the important documents, images, audio and video files that have been encrypted.
After the attack, it is almost impossible to open or use any of the affected files because the Ransomware usually changes their file extension and make them unrecognizable for the system or any other software. What is more, the malware may automatically start with Windows every time it launches and may attempt to encrypt other devices that are connected to the infected computer or the data that you have managed to restore. That’s why, if you want to continue to use your computer safely, we would highly recommend you not to pay any ransom but to remove the Ransomware with the help of the removal guide below. Unfortunately, it is not that easy to break the secret encryption and recover the affected files, but in the next lines, we are going to do our best to help you minimize the negative consequences of the .Arena Virus attack.
If you have been attacked by .Arena Virus, carefully research your options!
Ransomware, in general, is very tricky malware which has been making the news headlines with its newest and most sophisticated versions. The problem with threats like .Arena Virus is that they can sneak inside your computer practically undetected and can block the access to your files until you pay a certain amount of money (usually required as a Bitcoin payment) to the criminal creators, who stand behind the infection. The crooks target files which are commonly used in order to prevent users from accessing their most favorite and most needed data. Usually the affected files contain popular extensions such as .doc, .docx, .txt, .xls, .xlsx, .gif, .jpg, .png, .pdf, .pps, .ppt, .pptx, .odt, .db, .csv, .sql, .mdb .sm.php, .asp, .aspx, mp3, .mp4, .avi, .mov, .mpg, .html, .xml, .psd, .frm, .myd, .myi, .dbf, .rm, .wmv, .m4a, .mpa, .wav, .sav, .gam, .log, .ged, .msg, .myo, .tax, .ynab, .ifx, .ofx, .qfx, .qif, .qdf , .ncf, .nsf, .ntf, .lwp. When the encryption process is complete, .Arena Virus automatically generates a ransom message and places it on the screen of the infected computer. A short deadline is given to the victims to fulfill the ransom demands, otherwise, the hackers may not give them a decryption key with which they should regain their access. The amount requested may vary a lot and from a few bucks it may reach up to a couple of thousands, but we strongly discourage you to pay it, even if it is not that big because it may really not save your files. In most of the cases, the crooks vanish with the money the moment they get it and never send a decryption solution to the victims.
So, with this in mind, what we can suggest is that you remove .Arena Virus and rather invest your money in a good system protection than sponsoring the hackers and their criminal blackmail scheme. In the free removal guide below we have published the exact steps that you need to take in order to detect and eliminate the Ransomware. For best results, we recommend you scan your PC with the professional malware removal tool and combine it with the guide. Once you have removed the infection and all of its traces, we suggest you check all of your external devices and cloud storage for copies of your encrypted files. You may be able to recover some of them this way, or if you have a full file backup, that would be the best. In case you have no backups, unfortunately, there aren’t many options that can help you recover what has been encrypted, but you can give a try to our file-restoration instructions or contact a Ransomware recovery specialist for additional assistance.
.Arena Virus File Ransomware Removal
Prior to starting to execute the steps from the guide, we advise you to either bookmark this page or open it on a separate device since throughout the process of completing the guide, you might need to exit your browser.
1: Using Safe Mode
Before beginning to troubleshoot the issue, you are advised to enter Safe Mode on your PC. If you do not know how to do that, use this guide on how to enter Safe Mode.
2: Spotting the process
Open your Task Manager using the Ctrl + Shift + Esc key combination. Next, go to the processes tab and carefully look through the list for any shady entries. Usually, malicious processes will be consuming large amounts of CPU and RAM and will either have no description or will have a suspicious-looking one.
Once you identify the virus’ process, right-click on it and select Open File Location. Delete everything in the folder that opens if you are sure that the process was malicious. If you are not sure, contact us in the comments.
Go back to the Task Manager and end the potentially harmful process.
3: Hosts file IP’s
Go to your start menu and in the search field, paste the following address: notepad %windir%/system32/Drivers/etc/hosts. Select the first result and look at the bottom of the newly opened notepad file. See if there are any IP’s below “Localhost” and tell us in the comments if there were any IP addresses.
4: System Configuration Startup Programs
Type System Configuration in the Windows search bar and open the first result. Go to the Startup tab and take a look at the list of startup programs (on Windows 10, the Startup programs can be seen in the Startup Section of the Task Manager). If any of them look shady or have unknown manufacturer or a manufacturer with a sketchy name, uncheck those entries and click on OK.
Open the Run window (WinKey + R), type regedit and press Enter. Once the Registry Editor opens, press Ctrl + F and type the name of the virus. Select Find Next and delete whatever gets found that has the virus’ name. Do that with all search results.
6: Deleting potential virus files
Open the Start Menu and separately type each of the following locations: %AppData% %LocalAppData% %ProgramData% %WinDir% %Temp% . Open each of those folders and sort their contents by date. Delete the most recent files and folders. When you open the Temp folder, delete everything in it.
