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.

Cring is categorized as a ransomware-type virus that encrypts personal data of various sorts (images, videos, documents, etc.) To make the encryption successful, Cring applies special cryptographic algorithms, which establish strong cipher protection. All of this is accompanied by the assignment of the ".cring" extension, which is added to the end of each file. As an example, the original piece like 1.mp4 will be changed to 1.mp4.cring and reset its icon. Whilst this process is underway, the virus prepares to drop a text file (!!!!deReadMe!!!.txt) containing ransom instructions. Inside of a document, extortionists are straightforward saying that your files are impossible to unlock on your own. The only solution is to contact developers and pay a fee of 2 bitcoins. Unfortunately, because the infection is very new to the ransomware world, cyber experts have not found a way to decrypt it for free just yet.

If you see your search engine changed to Searchlee.com, then more likely you are dealing with unwanted software categorized as a browser hijacker. Such programs target unprotected systems to impose additional features. Although they are presented as something useful, the real value of such is next-to-nothing. In contrast, Searchlee.com can be harmful to your privacy as it has access to recording your personal data. In other words, if you let it run on your PC for too long, the data like passwords, IP-addresses, and geolocations may leak into fraudulent hands. Thus, we call you into deleting this browser hijacker to restore online safety. Follow our guide below to learn the removal instructions.

A new ransomware infection known as DEcovid19 has come to the web and caused a lot of attacks on unprotected PCs. The virus was reported on 11th January by desperate victims with data encrypted. Based on current information, it is clear that DEcovid19 blocks access to data by changing file extensions to .covid19 or .locked. An example of the original 1.mp4 impacted by ransomware may appear in two ways: either as 1.mp4.locked or 1.mp4.covid19. Once the encryption process gets to a close, the malicious program creates a text note (!DECRYPT_FILES.txt or ATTENTION!!!.txt) meant to explain decryption instructions. Inside, users can see a quick skim through the virus information. The next part of the text is dedicated to restoring your data. Users are said to contact the telegram bot attaching personal ID in the subject line and writing how many PCs need to be decrypted. It is also necessary to send 1-2 encrypted files that do not contain important information (less than 2MB) so that cybercriminals could match up the right decoder for your data. The last, but not least said by swindlers is time boundaries - you have 72 hours to make a decision and pay for the decryption key.

Being a suspicious website with adware capabilities, Epicunitscan.info promotes advertising content via the desktop of users. This domain may appear at browser startup because of adware installed in your system. Therefore, an unwanted program hijacks your browser settings to exhibit malicious pop-ups (notifications) on desktops and during the browsing session. Epicunitscan.info is not something you should be comfortable with. It can potentially spy on your data and collect sensitive information (IP-addresses, geolocations, passwords, etc.) for selling purposes. In addition to that, content advertised by Epicunitscan.info can lead to adult pages, peer-to-peer websites, "free-to-download" pages, and other suspicious resources like that. This is why it is important to prevent redirects originating from Epicunitscan.info to restore your safety. In order to do this, we recommend following our instructions below.

istart.webssearches.com is part of unwanted software classified as a browser hijacker. The app gets installed in your system and changes some browser segments. To elaborate, it alters your homepage and search engine to istart.webssearches.com. The visual part of the start page is also added with shortcuts redirecting to popular web-sites, shopping platforms, and games. At the bottom of your homepage, you can also spot that istart.webssearches.com is developed and released by EMG Technology Limited. Although istart.webssearches.com is not a virus, it does not bring any beneficial impact on users' experience. On top of that, if you dig deeper into permissions provided to istart.webssearches.com, you will then realize that it can track your personal data. Because there is no evidence towards the trustworthiness of this program, not excluded that developers run data collection (IP-addresses, geolocations, passwords, etc.) alongside the browser usage. This is why it very reasonable to get rid of istart.webssearches.com to restore safety around the web. Detailed instructions on the removal can be found in the article below.

The Malwarebytes experts have classified Best Searcher as another browser hijacker, which manipulates browser settings in favor of various changes. To be more precise, it changes your homepage domain to mh.aatub.xyz and affects some visual adjustments to the start page of your browser. Whilst all of these changes are meant to improve the browsing experience, our investigation proves completely the opposite. Best Searcher does not generate unique results, instead, it might mimic the capabilities of legitimate search engines (Google, Yahoo, Bing, etc.) to show ostensibly better results. Using Best Searcher makes no sense as it also causes redirects to other suspicious pages, which contain dangerous content. A number of ads and banners being displayed along with the usage, can gobble up system resources and downgrade your system significantly. The last, but most important thing to mention is data-tracking abilities. Browser hijackers do not guarantee any privacy terms. This is why your data may be at risk of being spied by Best Searcher developers. If you suspect something is wrong with your browser, we recommend you get rid of the program causing the above-mentioned changes. Our guide below will show how to do this.

Fair Ransomware is one of many dangerous pieces that encrypts personal type of data. It belongs to the malware family known as Makop, which has developed a number of similar infections. Once Fair Ransomware attacks your system, it installs certain scripts, which block access to multiple files by assigning unique extensions. These extensions consist of a personal ID number, [fairexchange@qq.com] suffix, and .fair at the end of each file. An example of the original sample that experienced these changes looks like this 1.mp4.[9B83AE23].[fairexchange@qq.com].fair. Whilst the access to data is no longer in users' hands, extortionists create a text file called readme-warning.txt in each folder containing encrypted files. Inside of this note, cybercriminals briefly explain to confused people what has happened to their PCs. Then, the creators of Fair Ransomware tell it is necessary to buy the decryption software (in BTC) to regain control over the data. They also offer to take part in the so-called "guarantee check", allowing users to decrypt 2 files of limited size for free. Unfortunately, even though such tricks should justify the integrity of swindlers, statistics are out to say the opposite.
