How to remove Kcbu Ransomware and decrypt .kcbu files

0
Kcbu Ransomware is another representative of STOP/Djvu virus, that has been tormenting users since 2017. This particular version was released in the end of November 2022 and adds .kcbu extension to all encrypted files, as can be seen from its name. Other than that, it's the same file-encypting and ransom-demanding virus as hundreds of its predecessors. Ransomware of this type uses the same cryptography, that is, unfortunately, still undecryptable. The only things that change during last years are extension and contact e-mail addresses. The name of the ransom note remains unchanged (_readme.txt) and you can check the content in the text box below.

How to remove Captchafine.live

If you see your browser session redirected through Captchafine.live, then it is likely because your system is being affected by adware, or you unintentionally subscribed to its notifications. Such websites are usually meant to generate revenue for their developers by displaying unwanted ads, banners, coupons, pop-ups, surveys, fake lottery pages, adult websites, online web games, casinos, and various similar resources. Potentially Unwanted Programs like adware could sneak into the system without your consent while installing third-party programs. Software that runs dubious advertising campaigns may also have access to the entire browsing activity. In other words, there is a chance of being tracked by the developers for passwords, geolocations, IP addresses, and other sensitive information to sell it afterwards. Considering such a number of threats, Captchafine.live, and its adware must be removed from your PC without traces to restore safe browser usage. We will help you do this in the article below.

How to remove Onelock Ransomware and decrypt .onelock files

0
Onelock is a ransomware infection developed by the Medusa ransomware family. Its purpose is to encrypt access to potentially important data (using RSA and AES encryption algorithms) and extort money from victims for full decryption. While rendering files inaccessible, the virus adds the new .onelock extension, which would make a file like 1.pdf change to 1.pdf.onelock and reset its original icon. The same pattern applies to other files that get targeted by the infection. After successful completion, Onelock creates the how_to_back_files.html file to feature decryption instructions. Overall, it is said that ransomware developers are the only figures able to decrypt victims' data. For this, victims are therefore instructed to contact cybercriminals using a chat link in Tor Browser (or e-mail) and pay some specified amount of ransom.

How to remove Mobilisearch.com

0
Mobilisearch.com is a suspicious browser domain that may replace your default homepage in case you have unwanted software or extension installed on your PC. Software that promotes such browser changes is usually categorized as browser hijackers. Many homepage domains promoted by browser hijackers do not have their own search engines and eventually redirect users to legitimate engines like Ask, Yahoo, Bing, Google, and so forth. This indicates the installed extension/program does not have any value at all and is only likely to deter users' experience. For instance, those experiencing Mobilisearch.com or other dubious addresses may also be subject to facing a number of suspicious ads or forced redirects while browsing the web. The displayed content is therefore likely to be unwanted and lead to explicit or compromised pages promoting fake updates, low-quality software, or online scams. In addition, a program or extension that modified browser settings without your consent may also be able to track and gather browsing-related information, such as passwords, IP-addresses, geolocations, and other kinds of data. Note that browser hijackers and other unwanted software often make it hard to perform manual deletions of assigned changes. This is because they tend to install certain registry values that prevent traditional roll-back of changes. It is common to see a setting called "managed by your organization" in this case. Follow our guide below to remove the unwanted software/extension and restore the default settings of your browser (Google Chrome, Safari, Firefox, and Edge).

How to remove Kcvp Ransomware and decrypt .kcvp files

0
Kcvp Ransomware is a high-risk file-encrypting computer virus, that belongs to notorious family of STOP/Djvu. Here are some of its characteristics: it modifies files' extensions with 4-letter code .kcvp; it encrypts those files with strong combination of AES-256 and RSA-1024 cryptography; it creates ransom note _readme.txt, where authors demand $980/$490 ransom for decryption. Unfortunately, full decryption is not possible if the virus used online key (your PC was online during the whole process of encryption). But do not despair, there are still chances to restore data partially or even completely with instructions provided on this page and certain portion of luck. The hackers offer to decrypt 1 file for free, and we recommend not to miss this opportunity. Although, they say file must not contain important information, send them 1 crucial file, most important document or memorable photo. However, that should be all communication with them. Do not pay the ransom, because, in most cases, malefactors just stop responding. Before proceeding with any decryption instructions in this article, you need to remove the actual virus and make sure it will not return. Use one of the removal tools provided, or any decent antivirus of your choice. Then, we recommend copying any untouched data to an external drive. Now you can start attempts to recover the files.

How to remove InputActivity (Mac)

0
InputActivity is labeled as a potentially unwanted app that often installs on macOS without users' consent. This piece of software was discovered to display dubious ads (banners, surveys, pop-ups, coupons, etc.) and assign a fake search engine that replaces the default homepage. Such functionalities are often inherent to adware and browser hijackers. The dubious ads displayed by InputActivity can therefore lead to potentially dangerous pages that try to bait users into downloading malicious/unwanted software, display adult content, or make users become victims of scam/phishing techniques. As mentioned, search engines assigned by browser hijackers are considered fake and this is because they are often unable to generate their own results. Instead, browser hijackers typically use legitimate engines like Google, Yahoo, Bing, or others to feature the search results. Another potential threat that may be posed by unwanted software like browser hijackers is data surveillance. Upon installation, the app or extension may modify browser settings in a way to allow the collection of sensitive browsing data, such as IP-addresses, geolocations, history, cookies, and other types of information that cybercriminals might sell to third-parties afterwards. Although InputActivity is not classified as malware, its capabilities are still enough to create privacy/identity threats for users being affected by it. Thus, we strongly advise you remove it using our instructions below.
