How to remove Bonsoir QNAP NAS Ransomware and decrypt .bonsoir files

0
According to recent forum reports, users are dealing with a new ransomware infection known as Bonsoir. This virus targets local networks (NAS, QNAP, Samba/SMB, Synology) encrypting the stored data with AES-CFB algorithms. The decryption of files is thereby offered inside of a text file called HOW-RECOVER-MY-FILES.txt. To elaborate on data encryption, we should mention that Bonsoir applies a one-word extension to each piece of data - .bonsoir. For example, if there was a file named 1.mp4 in your storage, it will change to 1.mp4.bonsoir as a result of infection. Developers of the virus claim their instructions to be the only solution towards restoring your files. One of the victims actually emptied his pockets and bought the decryption key imposed by extortionists. He, therefore, managed to recover his files with the provided key. Unfortunately, this method does not fit everybody because of the high amounts required by cybercriminals and the risk to be fooled by them. This is why our advice is to delete Bonsoir QNAP NAS Ransomware and try using legitimate utilities to access your data.

How to remove Bestcaptcharesolver.com

0
Bestcaptcharesolver.com is one of many rogue websites that promote fake push-notifications. By displaying the message to "Confirm that you are not a robot", the suspicious page allures people into clicking on the "Allow" button. Although this button is claimed to be meant for confirming the above-mentioned, its actual purpose is to enable and deliver dubious pop-ups to users' desktops. Unexperienced users usually get caught off guard by that trick. Some might even ignore the appearance of unknown content and take it for granted. This might be a fatal mistake since such ads promoted by Bestcaptcharesolver.com can lead to potentially dangerous websites. Also, if you see Bestcaptcharesolver.com each time at browser setup, more likely your browser is monitored by somebody else. Thus, your data and other information entered throughout the browsing sessions can be hijacked and sold to cybercriminals. This is why deleting Bestcaptcharesolver.com from your system is urgent. Our guide below will show how to do this in just a couple of steps.

How to remove PC HelpSoft Driver Updater

0
PC HelpSoft Driver Updater is presented as a helpful tool meant to improve computer performance by updating drivers. Unfortunately, its "useful" capacity is suspected to be suspicious, therefore, it is categorized as a Potentially Unwanted Program. Alike other similar programs that are trying to mimic the capabilities of leading software within PC optimization, PC HelpSoft Driver Updater cannot be trusted as claimed. Although it may provide correct information about outdated drivers and other useful features, there are many drawbacks that should suggest its urgent removal. First of all, an app like PC HelpSoft Driver Updater is usually installed against users' will. This means that your system has been intentionally invaded by unknown software. Then, most of its capabilities become available only after completing a purchase. Moreover, it might install certain entries in order to harden the process of uninstallation for inexperienced people.

How to remove Cadq Ransomware and decrypt .cadq files

0
If unexpectedly the names of your files changed, .cadq is added at the end of their name, and the files themselves stopped opening, this means that your computer is infected with the file-encryption virus called Cadq Ransomware (STOP Ransomware). Using a strong hybrid encryption system and a unique key, this virus encrypts all files located on the infected computer. Each encrypted file receives new extension: .cadq. To encrypt data, the parasite uses a combination of AES and RSA algorithms. New versions appear almost every week, although they all show their activity according to the same template. Even if you delete the new extension or completely rename the file, it will not help restore access to its contents. Only the key and decryptor that the authors of the Cadq Ransomware have can decrypt the files. Fortunately for the victims of this virus, a free decryptor was created, which in some cases can help decrypt affected files. After encryption malware places special text file with instructions to pay the ransom (ransom note), called _readme.txt in each folder.

How to remove Firesear.ch

0
Firesear.ch is an unwanted program categorized as a browser hijacker. The most obvious trait of it running on your PC is the assignment of Firesear.ch instead of your default search engine. In other words, once you enter a word in the search bar, the query will be redirected through Firesear.ch and other suspicious engines. Such changes are usually made to generate illegal traffic for revenue purposes. The appearance of the infected browser looks almost identical to the original one. The only thing changed is new icons allowing to access popular platforms (e.g. Amazon, Facebook, etc.). Also, you may spot the "Managed by your organization" text line in the browser menu, which is displayed in case your browser is accessed by third-party organizations. All of these changes entail no good purpose as browser hijackers can track your personal data and sell it to cybercriminals. To prevent this, we recommend you get rid of Firesear.ch as soon as possible. Our guide below will show precise steps to do so.

How to remove Cuba Ransomware and decrypt .cuba files

0
Cuba Ransomware is a malicious program, which uses a set of cryptographic algorithms to encrypt personal data. The virus has been seen in different versions with different styles of encryption. They might differ by ransom instructions, but usually, all of them apply the same .cuba extension and FIDEL.CA file marker in the header. For example, an infected file like 1.mp4 will transform and start looking like this 1.mp4.cuba or similar. Then, once the encryption is up, Cuba drops a text file stating how to decrypt your data. Many victims have received various instruction samples (!!! ALL YOUR FILES ARE ENCRYPTED !!!.TXT). In most of the cases, all of them tell victims to contact the attached e-mail with their personal ID number. After this, people will get the necessary steps to run the payment and retrieve the decryption tools promised by the developers. Unfortunately, statistics upon successful decryption are pretty poor. This is because there are potent ciphers applied to the files, which makes it hard to decrypt them.
