Is This Virus Irritating?

Your files are encrypted by Cerber Ransomware 4.1.0 ? Check our guide for instructions on the removal and file recovery of Cerber Ransomware 4.1.0!

If you suddenly realized that your personal files have been locked by some strange encryption that your PC is unable to read and after a while a message popped up on your screen telling you that you need to pay ransom if you want your data back, then you have likely fallen victim to a virus called Cerber 4.1.0. This particular piece of malware is one of the newest members of the Ransomware family.

Introduction to Ransomware

If this is the first time you hear about Ransomware, you should know that these malicious programs are currently one of the greatest online security hazards. They target both big company conglomerates and normal users. Nobody is safe from a Ransomware attack and due to the whopping pace of evolution of these noxious programs, it is often next to impossible to stop them once they’ve gotten inside the system. That is why we strongly recommend that you carefully read the following article, since it will provide you with essential information concerning Cerber 4.1.0 and the rest of its type. Apart from that, there is a guide that may help you remove such malware from your machine if it has already been infected by it. However, keep in mind that, as we mentioned, there are no guarantees with Ransomware viruses and what had worked a day ago might prove to be ineffective today.

Understanding Ransomware

In order to get a better idea of why this particular type of malicious software is so problematic, you’d need to understand how it functions. Unlike other more conventional viruses, Ransomware programs do not actually strive to harm your system or data. The method they use to lock your data is called encryption and it is not an inherently malevolent process. Many legal programs use encryption to protect their files. This has led to anti-virus software being programmed to ignore encryption processes, regarding them as safe and non-threatening. This, in turn, is the perfect opportunity for programs such as Cerber 4.1.0 to operate under the radar of most scanner tools. However, unlike normal programs, Ransomware targets all of the user’s personal files. Once the encryption is done, you are unable to access any of your data. Usually, at this point the virus reveals itself via a ransom-demanding message displayed on the victim’s screen. The message oftentimes provides detailed instructions on how the user is supposed to pay the money, in order to be sent the decryption key for that would allow the computer to regain access to the locked data.

Bitcoins and Ransom payment

It is generally a very bad idea to opt for the ransom payment. There is just no guarantee that you wouldn’t actually be wasting your money in return for nothing. After all, nobody can oblige the criminal to send you the encryption key. Here, it should be mentioned that in the majority of instances the Ransomware blackmailers require the payment to be made in the form of bitcoins. This is a cryptocurrency that is virtually untraceable, which in turn allows the criminal to remain anonymous. Therefore, if you make the transfer, there is little to no chance that you’d ever get the chance to sue the hacker, let alone return your money. Our suggestion to all victims of a Ransomware attack is to seek another method of handling the situation. Our guide is one possible alternative, which could potentially help you remove the nasty virus from your machine and restore your data.

How to detect Cerber 4.1.0 (manually)

As we already mentioned, anti-virus software might prove ineffective when detecting different Ransomware viruses. However, the encryption process can be manually spotted if the user is vigilant enough and knows what to look out for. Know that the virus might need a considerable amount of time to lock all your files. This is because in order to encrypt them, the Ransomware first needs to copy each and every file. Those copies are actually the files that have been encrypted and not the originals. After this stage is over, Cerber 4.1.0 deletes the original data and you are left with the inaccessible copies. This is how the encryption works and during the time the process is taking place, significant amounts of PC resources such as RAM, CPU and free storage space are going to be used. Therefore, if you notice unusually high levels of system resource usage for no visible reason, then there might be a Ransomware infection. If this is the case, quickly shut down your machine and have it examined by a specialist. Also, remember not to connect any USB devices for a last-minute back-up, because they could also get infected by the Ransomware.

Protection tips

By now it should be fairly obvious just how nasty this type of malware is. Therefore, keeping your system safe and secure is the only truly effective way that would prevent your data from getting locked. Here are a couple of useful pieces of advice that will aid you in protecting your machine in the future:

  • Make sure to install a high-quality security program, since oftentimes Ransomware makes its way into people’s computers with the help of other backdoor viruses, such as Trojan Horses. Also, some newer and more advanced anti-virus programs have certain levels of Ransomware detection, which is worth having at your side.
  • Do not download anything from unreliable sources or ones that are illegal. Only visit reputable websites that you know you can trust and stay away from the shadier parts of the internet.
  • Never open any suspicious e-mail letters that get sent to you or download any files attached to them. Do not click on any obscure-looking hyperlinks. Those are some of the most common ways for Ransomware distribution.
  • Backup all your important personal files on a separate device that is not connected to the internet and frequently update that back-up with any new valuable files that you might have.

Is This Virus Irritating?

In this article we are going to try and help you remove the .Shit File Virus Ransomware. Our instructions cover all Windows versions.

.Shit File Virus is the newest iteration of the well known Locky ransomware

The viruses belonging to the Ransomware family are especially harmful and bothering, because they cause real encryption of files. After that, they are programmed to demand ransom for recovering the encoded data. To top it all off, they are extremely difficult to be dealt with and their consequences are especially hard to be reversed. The program described in the paragraphs below falls into that category exactly. Its name is .Shit File Virus and its characteristics have been discussed in detail.

The .Shit file extension might sound like a joke, but it isn't.

A Sample .Shit file created by the Ransomware

Ransomware Trivia

The viruses identified as Ransomware first emerged in Russia approximately in the last two decades of the 20th century. In the beginning there used to be two distinct types of Ransomware-based viruses:

  1. File-encrypting– the category .Shit falls into. These programs are known to infect machines and then scan all their disks for the most regularly used data. All these files get encrypted later with a special key formed by two components – a private and a public one. The Public one is available to the affected user as soon as the virus has completed its terrible encrypting mission. The second part – the Private key – is offered to the user via a notification that appears at the end of the encoding process in exchange for a ransom. All the payment details are also included into that notification.
  1. Screen-blocking – the viruses belonging to that group are known to sneak into computers in the same way as the ones from the other subtype. The difference between these two subtypes is that the screen-locking type could only block the user’s monitor with a big-size ransom-requiring message. In fact, no files have been encoded, just the monitor is blocked. However, ransom is again demanded from the affected users. Again, all the information regarding payments is available in the ransom notification.

After that, some more types of Ransomware have appeared, with slightly different target groups and intentions:

  1. Ransomware targeting mobile devices – Ransomware-based viruses could also infect smartphones and tablets. In such a case, the way the virus functions resembles the one the second subtype described above uses – the screen-locking one. Only the display of the infected device gets locked up and money is demanded for making it accessible to the victim user again. No data gets encrypted and is in real danger.
  2. Some viruses based on Ransomware get exploited to make hackers pay for violating the law – some programs based on Ransomware get used by government security agencies to make cyber criminals pay fines for breaking some law, for example, copyright regulations.

How does such a virus get distributed?

.Shit, as well as most of the other Ransomware versions, has many different means of distribution. They could be hiding inside emails, as well as email attachments. In this case they are usually accompanied by a Trojan horse virus, which ensures their arrival to your system, as it uses a vulnerability to let them in. Another very common source of such malware is the so-called malvertising. Some web pages contain malicious advertisements and once you click on such, you get contaminated automatically. Other potential means of distribution could be drive-by downloads from contaminated web pages; also some contagious torrents and shareware.

Can .Shit Virus be safely removed? Can the encrypted .Shit files be saved?

When it comes to infections caused by Ransomware-type viruses, it is essential that you remember that no action could really guarantee you the recovery of the locked-up data. Even if you manage to get rid of this threat, your encrypted files might get lost for good.  Even if you DO pay the hackers, they might decide to disappear with your money and leave your files inaccessible forever. As the chance for success in such a case is really small, we recommend that you wait before completing the ransom payment. You lose nothing if you try to save your data in a different way from just complying with the demands of some harassing cyber criminals. What you can do if you make a decision to try to get the issue solved on your own is to contact someone who has some experience dealing with such problems. An expert could have valuable knowledge and even some secret ways of fighting viruses like .Shit. Again, don’t expect to restore your files easily even if you hire a professional. Another possibility is to try to use a removal guide. That’s why we have assembled one for you. Scroll down and find our Removal Guide. It will guide you to removing the virus and it might even help you restore your data. Always remember that in the fight against Ransomware, your strongest weapon will always be prevention. The most efficient prevention method is just learning to regularly back up your files, so that you always have copies and no one could ever harass you by using them.

Is This Virus Irritating?

This page will help you with the removal of Fileless Malware. The Fileless Malware is a new breed of a Trojan horse computer virus.

In the article below you will find all the information about the infection with Fileless Malware (a version of a Trojan horse), as well as some details about this virus’ characteristic features. We are also going to suggest a way to remove such a contamination. 

Trojans: not myths, but real cyber nightmares

These cyber threats have been named after the mythological Trojan horse that won the victory for Greece in the Trojan war. However, they are truly dangerous, not just subjects of stories. If you are wondering why these viruses have received that common name, the reason is that they act just like the horse from the myth – they use a weakness in your system to get inside. Once there they wait until the circumstances are perfect and they attack what they have been programmed to attack on your PC. Then you end up infected and probably experiencing terrible consequences and you have no idea how that contamination had occurred. Trojans are probably the favorite tools of hackers all around the world, because they can be used for a variety of different purposes and with many various intentions. These viruses are really capable of performing anything once incorporated into your computer. That is why we are describing them in general here, not just Fileless in particular. They could indeed be responsible for the following negative consequences and many more:

  • An infection with a Trojan might cause corruption or destruction of files. This kind of malware is often exploited by hackers just to have fun. What we mean by this statement is that cyber criminals are delighted when they delete files, corrupt data or destroy an entire system. For that purpose, they most usually use Trojans. This is kind of like a hobby for them. That’s why you shouldn’t be surprised if as a result of the infection with Fileless, some of your files are lost or your whole OS gets destroyed.
  • Your PC might be turned into a bot and its resources might get exploited. One of the most likely usages of Trojans is for draining your computer resources for the purpose of distributing spam or mining cryptocurrencies. This means that your computer could be used as a bot as a result of the contamination with a Trojan.
  • The hackers might be after your identity or your money. Sometimes cyber criminals exploit Trojans with the desire to steal some money from innocent users. The virus is perfectly capable of remembering your key strokes, bank account credentials and other personal information that could later help the hackers drain your accounts and steal all your funds. Also, your identity might be in danger because the hackers harassing you might alter all the information about you online and might even commit some crimes on your behalf, which is more than scary.
  • The hackers may just want to spy on you. Some cyber criminals show signs of physically abusive or stalking-oriented behavior. They might spy on you using such a virus to control your machine remotely, turn on your microphone or camera and watch you 24/7. What’s really bothering is that such criminals might later become physical ones. And to top it all off, they will have all your private details such as address, occupation, appearance, etc.
  • The virus might be looking for classified information from the company you work for. Sometimes the criminals behind the virus are really interested in finding out some company’s classified data and they might use an employee’s PC to hack the professional network. They may have nothing to do with you personally.

Where can Fileless be found?

Fileless, just like most of the other Trojans, can most often be found together with a Ransomware variant as a component of a spam email or attachment (image, archive, .exe file) or as a drive-by download from following a malicious pop-up ad. Of course, there could be other various sources of these viruses like shareware, bundles, torrents and webpages, infected with them. It is very important that you stay as far away as possible from Fileless’s potential sources mentioned above. What else you need to do is to install the most powerful anti-malware tool available. Purchasing a top-quality anti-virus program will help you a lot against all kinds of threats. Just keep it up-to-date and use it regularly for scanning for malware. As for removing Fileless, we suggest that you implement all the instructions in our Removal Guide. Hopefully, you will get the chance to solve your issue and save your system from further damage.
