Hhoo has been classified as a ransomware-type virus, which encrypts personal data using cryptographic algorithms. Being yet another version of the Djvu/STOP family, Hhoo can target both individuals and organizations to demand high amounts of ransom. It appeared in the middle of February 2023 and hit thousands of users. Ransom is a so-called payment required by cybercriminals in exchange for the blocked data. Extortionists provide detailed information on that inside of a text note (_readme.txt) which is created after Hhoo ends up file encryption. The encryption process can be easily spotted by new extensions that are assigned to each of the files. This virus appends the .hhoo extension so that an encrypted piece ends up looking like this 1.pdf.hhoo.

Turaddoptle.com is one of many rogue websites that promote fake push-notifications. By displaying the message Click the "Allow" button to subscribe to the push notifications and continue watching, 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. Inexperienced 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 Turaddoptle.com can lead to potentially dangerous websites. Also, if you see Turaddoptle.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 Turaddoptle.com from your system is urgent. Our guide below will show how to do this in just a couple of steps.

CRYBrazil is a ransomware variant that was discovered by MalwareHunterTeam in 2018. This virus mainly targets Brazilian and Portuguese users in order to encrypt potentially important files and then demand a ransom for their decryption. While restricting access to files, the file-encryptor has been observed to assign .crybrazil or .hacked depending on what version penetrated the computer. Once the encryption is finished, CRYBrazil changes the desktop wallpapers to display decryption guidelines and also places the SUA_CHAVE.html file (which leads to a fake download page for Adobe Flash Player) in each folder containing encrypted data. This or other fake websites may therefore be used for distributing unwanted software or additional malware infections.

Hacktool:Win32/Keygen is a code-name referred to by anti-malware software when the usage/presence of license-cracking tools gets detected on the system. Such tools allow the fake generation of keys to activate licensed versions of software and therefore bypass paying for it. Although keygen tools are not intended to be harmful to users' safety initially, some threat actors may use them to deliver various malware alongside. While the detection and labeling of the cracking tool as "Hacktool:Win32/Keygen" by your antivirus does not always indicate your system is infected with actual malware, it still might be a good idea to perform a thorough scan of your system. Infections that can be distributed alongside key-generating tools are ransomware (software that encrypts data and demands money from victims), crypto-miners (software that stealthily mines cryptocurrency for cybercriminals), banking trojans, spyware, and other types of potentially devastating infiltrations. Having such malware installed on your system may lead to severe privacy problems, financial losses, downgraded PC performance, and other kinds of threats. Thus, if you recently used a license-cracking tool (Hacktool:Win32/Keygen) and suspect your system could be in danger, make sure to read our guide below and scan your system with effective anti-malware software to detect and eliminate possible threats.

Hhee Ransomware is a recent virus developed by the STOP/Djvu ransomware family. This group of developers has developed hundreds of ransomware infections designed to render personal data inaccessible and blackmail victims into paying the ransom. Hhee is not an exception as well. This is type of malware that encrypts the files on a victim's computer and demands a ransom payment in exchange for the decryption key to unlock them. It is also known as DJVU ransomware, as, first versions encrypted files with a .djvu extension. During encryption, it renames files with the .hhee so that a sample like 1.pdf will be changed to 1.pdf.hhee and reset its original icon. Immediately after this, the virus creates a text note called _readme.txt (example in the text box below), which contains file-decryption instructions. Currently, there are only few methods to decrypt data encrypted by Hhee Ransomware and chances are quite low. We provide all information in this tutorial.

Having files renamed with the .karen extension (like 1.pdf.karen) means your system is infected with Karen Ransomware. Ransomware is a malicious program usually designed to run encryption of data and demand money from victims for its decryption. After successfully restricting access to files, the virus drops the README.txt text note. However, unlike the majority of ransomware infections, Karen's text note is incomplete and does not contain any decryption-related information. The file-encryptor also opens a webpage with a field to enter UID (unique identifier), which is absent in the note as well. This means it would be impossible to contact the cybercriminals and pay the supposed ransom to return the data. The reason for that could be that cybercriminals released this ransomware as a premature version to test its functioning and effectiveness.

Captchacoolnow.top is another suspicious domain promoting spam notifications. Whether visited intentionally or not, users will see a pop-up window asking to allow push-notifications. This permission is ostensibly meant to confirm you are not a robot, pass Captcha, watch a video, download files, or other fake actions. In fact, after enabling web-notifications, your desktop will start receiving a continuous flow of banners, coupons, and other types of advertising content. Even if it seems innocent at first glance, there can be unwanted or malicious redirects concealed inside of them. This means that after clicking on such ads, you may end up on a completely different page you did not expect. Also, if you see Captchacoolnow.top each time at browser startup, your PC might be infected with adware that modified browser settings. Such changes mean that the infection may have access to surveil and gather personal data (passwords, IP-addresses, geolocations, etc.). Thus, based on all of these facts, we advise you to follow our guide below and delete a program that opens Captchacoolnow.top from your computer.

If you were attacked by the virus, your files are encrypted, not accessible, and got .hhmm extensions, that means your PC is infected with Hhmm Ransomware (sometimes called STOP Ransomware or Djvu Ransomware, named after .djvu extension, that was initially added to encrypted files). This encryption virus was very active since 2017 (.hhmm appeared in the middle of February, 2023) and has caused great financial damage to thousands of users. Unfortunately, there is very difficult to track down the malefactors, because they use anonymous TOR servers and cryptocurrency. However, with instructions, given in this article you will be able to remove Hhmm Ransomware and return your files. Hhmm Ransomware creates _readme.txt file, that is called "ransom note" and contains payment instructions and contact details. Virus puts it on the desktop and in the folders with encrypted files. Developers can be contacted via emails: support@freshmail.top and datarestorehelp@airmail.cc.
