Matroska Ransomware is a malicious piece aimed at data encryption. Matroska used to show its activity a couple of years ago until it went dormant. Within some time, it started a series of new infections on users' PCs. Whilst older examples of Matroska applied the .HUSTONWEHAVEAPROBLEM@KEEMAIL.ME, .happyness, .encrypted[Payfordecrypt@protonmail.com], .nefartanulo@protonmail.com extensions to encrypted files, recent attacks of this ransomware showed the new .siliconegun@tutanota.com extension being involved. Depending on which version impacted your system, a file like 1.mp4 will change to 1.mp4.happyness or 1.mp4.siliconegun@tutanota.com at the end of encryption. Once this process is finished, the virus goes further and creates a text file (HOW_TO_RECOVER_ENCRYPTED_FILES) with decryption instructions. Alike other ransomware infections, Matroska asks victims to pay a fee. The amount may vary from person to person, however, we do not recommend buying their software. Luckily, experts found that Dr.Web (leading antimalware software) is able to decrypt your data legitimately and risk-free. Before doing so, you've got to make sure you deleted Matroska Ransomware from your computer. Only then you can use third-party tools to recover the data. For more information on both removal and data decryption, follow the article down below.

DearCry Ransomware is a dangerous virus, which targets the encryption of personal data. Such malware makes everything sure that there is no way to decrypt the locked files. Knowing that, cybercriminals offer their own solution - to buy the decryption key stored on their servers. Because most users can find no way out of the trap, they agree on paying the ransom to recover the data. Unfortunately, this is a serious risk proven by multiple victims who did not receive the promised decryption. This is why it is better to delete DearCry Ransomware and reclaim your files via backup or data-recovery tools. If you are the one having files changed with the .crypt extension, which was then accompanied by the ransom note creation (readme.txt), chances are you are infected with DearCry Ransomware.

Developed on Node.js, JoJoCrypter is a malicious program that functions as a data-encryptor. A thorough investigation conducted recently shows there is a .jojocrypt extension assigned to each of the files. To illustrate, a non-encrypted 1.mp4 will turn into 1.mp4.jojocrypt as a result of infection. Along with this, it is also known that JojoCrypter uses RSA-2048 and AES-192 algorithms to cipher innocent files. It also creates a short ransom note how to recover your files.txt with following content. Unfortunately, the decryption with third-party tools appears to be an impossible task. The encryption chains are too strong and flawless to crack. This is why the only option (apart from paying the ransom) is to recover your files using backup or data-recovery tools. Otherwise, you will be forced to pay for the keys proposed by cybercriminals, which is mentioned in the ransom note dropped on your PC after encryption. Swindlers are not using too many words for describing what happened, instead, they attach their e-mail address to be contacted for further instructions.

Parasite is one of the newest ransomware samples detected by cyber experts in recent days. Alike other malware of this type, Parasite encrypts personal data and demands money for the decryption. However, it was found that Parasite has a significant flaw - it encrypts data with the wrong cipher and overwrites data with 256 bytes. This means that all data encrypted by Parasite loses its value completely, simply because it gets replaced with empty space. For example, a word file, which weighs megabytes of data will decrease and start weighing mere 256 bytes. Such a bug instantly shows that Parasite is not able to decrypt your files, simply because they become damaged. Of course, they claim to decrypt them in HOW_CAN_GET_FILES_BACK.txt ransom note (alternatively @READ_ME_FILE_ENCRYPTED@.html or info.hta), which is created after encryption, but it does not make any sense due to the above-mentioned.

Perfection is a ransomware-infection that involves RSA and AES algorithms to encrypt personal data. The purpose of such attacks is about capitalizing on desperate victims willing to restore their files. As a result, developers behind Perfection offer to pay for the decryption tool that will help you regain access to data. Before that, however, Perfection Ransomware appends the .perfection extension to each of the files. For example, 1.mp4 will change to 1.mp4.perfection and so on. Then, once this process is done, extortionists create a number of identical browser files and place them into folders with encrypted data. The ransom note created by Perfection is known as Recovery_Instructions.html.

There is a lot of Potentially Unwanted Programs strolling around the web. Big Linker is one of those using hijacking abilities to promote a series of suspicious content. It does so by linking your browser settings with fake search engines. Put differently, all of the queries entered during the usage will be redirected through chains of unwanted engines originating with keysearchs.com, my-search.com, and ending up with the legitimate Bing system. Browser hijackers tend to abuse a range of legitimate engines to generate illegal traffic. The presence of such changes impacting your PC can also spell the risk of data-surveillance. This means that Big Linker can record the data you use during the session (e.g. passwords, IP-locations, geo addresses, etc.). Based on everything mentioned, it is necessary to remove Big Linker to prevent privacy threats. Before doing so via our tutorial below, you can also get to know how Big Linker could infect your system.

SlimCleaner Plus is a PC optimization program that claims to extend battery, improve system performance, and so on. It does so by providing junk removal, registry cleaner, and other instruments meant to boost up your PC. Unfortunately, SlimCleaner Plus is not the most viable solution when it comes to system improvement. The app is more often categorized as unwanted software as it is distributed beyond the consent of users. Although SlimCleaner was reviewed by PCMag in 2016 and proven to be effective in some aspects of cleaning, most experts still doubt its boasted abilities. SlimCleaner also comes in a free version, however, it is hard enough to boost up your system. This is why developers offer to switch up to the paid version with unlimited access to all of its features. Our advice is to avoid spending money on such products, especially if you did not expect them to appear on your system. Therefore, our advice is to use wide-known utilities like IObit Uninstaller for making your computer a faster and safer place to work on. Below, you will find extended instructions on how to remove SlimCleaner Plus and find better alternatives to improve your system.

PDFConverterSearch is an unwanted application providing access to file-converting services right from the browser homepage. Whilst these features may be found useful for some of the users, PDFConverterSearch is still categorized as a browser hijacker. The reason for the poor reputation of such programs lies in their ability to spy on personal data and promote dubious content. For example, PDFConverterSearch changes your search engine to pdfconverter-search.com, which makes all of your queries redirected through it. Because pdfconverter-search.com is not capable of generating unique results, it channels your queries through legitimate Yahoo search to make illegal traffic. By doing so, developers are able to earn money on people who let PDFConverterSearch run on their system. To prevent this and similar applications from collecting your data, you are advised to remove it once spotted. Below, you will find the necessary tools to do it.
