One of the most harmful infections you can catch nowadays is named Rensenware Ransomware. This is a Ransomware cryptovirus, which is capable of causing serious damage to your files by encrypting them with a strong algorithm. Not only that, but it is an instrument of a blackmail scheme used by anonymous hackers and if you’ve been unlucky enough to get infected with it, you are now most probably blackmailed to pay ransom to them to access your data. How can you deal with that? Is there a way to remove the Ransomware and save your files? This is what we are going to explain you here, and if you don’t feel like paying any ransom to the unscrupulous crooks (which surely is not a good idea) then you can use the instructions in the removal guide below to detect and remove Rensenware from your system. But let us first tell you more about this malware and how it could possibly infect you.
How malicious Rensenware is and what could you do about it?
Rensenware is one of the freshly discovered Ransomware infections. It sneaks into your system silently and without asking your approval, it encrypts all the commonly used data on it. This way, it makes all your files unreachable and blocks your access to them. Once this is done, the malware generates a ransom message, where it places ransom demands. Basically, the hackers behind the infection blackmail you to pay ransom in exchange for a secret decryption key which can restore your files back to normal. They usually give you a short deadline to do that, and may also threaten you in various ways to ensure that you will be as stressed as possible and will pay them the ransom as quickly as possible, without having time to look for alternatives.
Indeed, you don’t have many options to choose from, once you have been attacked and your files have been encrypted with Rensenware. Unfortunately, the Ransomware encryption may be irreversible and neither the hackers, nor the security experts can guarantee you a full recovery from this type of attack, no matter what decryption solution they may offer you. Even if you pay the ransom, the decryption key may not work properly and may still not make your files accessible, not to mention that it is absolutely not sure that you will get one from the crooks.
However, there are a few things you could try in order to avoid the ransom payment and save some of your files. In the removal guide below we are going to show you a way to recover some of them from your system backups. We will also advise you to use some external backup copies from a cloud or a hard drive, if you have any, so you could minimize the data loss. However, it is not advisable to restore anything before you have fully eliminated the Ransomware from your system. If you do that, Rensenware may try to encrypt them again and this time, you may also lose your backups if the malware detects them. That’s why, once you’ve decided to go for this option, fist make sure you detect and delete all the Ransomware files from your computer. The removal guide below can help you do that, so closely follow its instructions to save yourself from the infection.
How can you catch a Ransomware infection?
The hackers, who create such threats, can be surprisingly creative when it comes to the distribution of Ransomware. A great number of infections usually happen through massive spam email campaigns and their malicious email attachments. In this case, the harmful payload is camouflaged as a harmless file, an ad or a link, which prompts you to click on it and this is how you catch the infection. A Trojan horse is also commonly used to help the Ransomware sneak inside your system undetected. It basically creates system vulnerabilities, which can easily be exploited by a threat like Rensenware and helps it remain hidden until it completes its harmful deeds. Malvertising is another very successful way of distribution. Fake ads, misleading links, too-good-to-be-true offers, free installers, torrents, and different compromised websites can be used to deliver the Ransomware to your machine. All that is needed is for you to click on one such transmitter, and you won’t even realize that the infection has taken place. That’s why we strongly advise you to avoid interacting with such sketchy content as much as possible. Of course, having reputed antivirus software is a must and updating your system to the latest security patches will ensure better safety. It may not guarantee you 100% of protection, but it may still minimize the chances of bumping into such threats too often.

Go to your start menu and in the search field, paste the following address: notepad %windir%/system32/Drivers/etc/hosts. Select the first result and look at the bottom of the newly opened notepad file. See if there are any IP’s below “Localhost” and tell us in the comments if there were any IP addresses.
4: System Configuration Startup Programs
Type System Configuration in the Windows search bar and open the first result. Go to the Startup tab and take a look at the list of startup programs (on Windows 10, the Startup programs can be seen in the Startup Section of the Task Manager). If any of them look shady or have unknown manufacturer or a manufacturer with a sketchy name, uncheck those entries and click on OK.
Open the Run window (WinKey + R), type regedit and press Enter. Once the Registry Editor opens, press Ctrl + F and type the name of the virus. Select Find Next and delete whatever gets found that has the virus’ name. Do that with all search results.
6: Deleting potential virus files
Open the Start Menu and separately type each of the following locations: %AppData% %LocalAppData% %ProgramData% %WinDir% %Temp% . Open each of those folders and sort their contents by date. Delete the most recent files and folders. When you open the Temp folder, delete everything in it.
