You keep all of your valuable data on your PC, don’t you? All of your fancy pictures with dear memories, the work files and projects, the favorite games, the music and video collections and a bunch of other useful and not so useful stuff. It is true – nowadays digital data represents a great share of our life. And a great target for the unscrupulous hackers who created .Oldbat. This new threat comes as a new addition to the infamous Ransomware family. It has been created with the sole purpose of encrypting all the files, found on the infected computer, and then asking the victim user to pay ransom in order to release them. How can one handle such a nasty threat? Can it be removed? Is there a way to regain access to the encrypted files without paying the ransom? The answers to all these questions and more you will find in the next lines.

How does Ransomware operate?

It is unthinkable not to have access to your precious data and most of us would do almost anything to get it back. This is exactly what lies in the core of the Ransomware blackmail scheme. The criminal hackers create threats like .Oldbat to extort money out of different institutions, businesses, and even regular online users, by blocking their access to their own data and ruthlessly blackmailing them to pay huge amounts of money for the decryption of the files. If your computer has been attacked by .Oldbat, now you are probably facing a disturbing ransom note on the screen, asking you to pay a certain amount of money, usually in Bitcoins, for a secret decryption key. This is how the criminal scheme usually works and, unfortunately, nowadays Ransomware has become one of the favorite quick money schemes for a number of hackers. 

But how exactly does the malicious encryption happen?

Unfortunately, a Ransomware threat like .Oldbat, which is by far one of the latest and most advanced one, is really hard to be detected. It hides in various types of online content such as torrents, spam emails, malicious attachments, fake ads, misleading links and even Trojan horse infections. The encryption it uses is a very complex one and it manages to remain under the radar of most security software. That’s why most of the victims come to know about the infection only after it has already encrypted their files. Hardly any visible symptoms may indicate the presence of .Oldbat on your machine. It has been developed in such a way, that it can hide deep inside the system and silently perform its harmful locking algorithm to each and every one of your files. Once it has encrypted everything, however, the Ransomware will not hide anymore and will reveal itself with a ransom message. There, the hackers, who stand behind the threat, usually place all their ransom demands, deadlines and instructions.

Is there a way to regain the access to the encrypted files without paying the ransom?

In this case that your computer has been attacked by .Oldbat, here is a solution that we have for you. Use the special removal guide at the end of the page. It can help you remove the nasty Ransomware form your system. However, we need to warn you that this cannot guarantee that everything will be brought back to normal just as it was before the attack. Unfortunately, after such a sophisticated encryption like the one that .Oldbat uses, most of your files may not be able to recover and may still remain inaccessible. But once you clean the infection, you can try to restore some of them with the help of the instructions in the guide, or from some external copies. We believe this is a better option than paying ransom to the criminals. In fact, you will risk nothing if you try, but you may really lose your money if you pay to the hackers. After all, who can guarantee that these unscrupulous criminals will really send you a decryption key? And what if they simply disappear? You may still not be able to get your files back, but your system will remain heavily compromised with the nasty malware on it and a couple hundred of dollars less in your account. Don’t sponsor the Ransomware creators! Try to solve the problem with all other possible options. The free removal guide below is one of them. If you are unable to handle the infection on your own, then think about contacting a professional or using the help of specialized software. This may still be able to help you more than giving your money to some anonymous criminals.
