Every day more computers get infected by viruses of the malicious Ransomware type. Today, this is arguably one of the worst security problems that both normal users and big companies and organizations are faced with. Once inside your computer, Ransomware will attempt to lock all personal data via a sophisticated encryption. Once your files have been encrypted, a ransom payment is demanded in exchange for the decryption key that will allow you to regain access to the locked data. Lately, there have been a lot of reports regarding yet another newly created Ransomware named CryptoLuck. Here, you will be taught all you need to know concerning viruses like CryptoLuck and how you can deal with them if they come your way. Also, for our readers, who have already had their data encrypted, we have a removal guide that may help restore things back to normal. However, note that going through with the Ransomware removal guide won’t be enough to effectively handle the threat. A good understanding of how these viruses work is essential for your computer’s future protection. Therefore, make sure to read the whole article and not only the guide manual.

What method Ransomware viruses use and why this is important

The approach that most Ransomware, CryptoLuck included, adopts is a very different and unique one in comparison to other types of malware that you might encounter online. Instead of directly attacking your system or files, most Ransomware viruses do not actually damage anything. As we already mentioned, encryption is used to lock your documents. What’s important to know about encryption processes is that they are not inherently malicious. It’s not uncommon that legit programs and applications actually use encryption to protect their own data from being corrupted. This is where the key to the success of Ransomware viruses lies. Most anti-virus programs allow any encryption processes that are currently underway on your PC to continue because they are not seen as security threats. This is what enables CryptoLuck to remain undetected until it has rendered your data inaccessible. Once the encryption is fully completed, the virus itself notifies you about what has just happened via a message displayed on your monitor. The notification note tells you that in order to receive the key, you will need to pay a certain amount of money to the hacker behind all of this. There’re usually instructions on what you need to do in order to make the transfer.

How you can stop the virus before it is too late

Encryption takes time and needs to undergo several different stages to be completed. First, all targeted files are copied and encrypted by the Ransomware code. After this is done, your original data is deleted. In the end, you still have an intact copy of each deleted file, however they are all locked by an encryption. During the time the process needs to be finished, CryptoLuck requires substantial amounts of CPU, free disk space and CPU time to complete its malicious task. If you are vigilant enough, it is technically possible to notice the virus’ activity before it is too late. If you manage to spot the infection before all data has been locked, make sure to shut down your PC and disconnect it from everywhere. Then seek professional help and maybe some of your files might be saved from the Ransomware’s encryption.

What about the ransom?

Many users have asked about whether it is a good idea to simply pay the ransom and get it over with. Our advice for those of you, who might be contemplating making the transfer, is to seek another way to handle the situation. Not only can you never be sure that you will actually receive the decryption key, but also, by paying the money, you will greatly encourage the hackers to continue blackmailing more and more users. Our suggestion for you is to use our guide and see if it solves your problem. While we cannot guarantee that it would help everyone, it is still a much better course of action compared to paying money to criminals.

Security tips against Ransomware

It’s safe to say that malicious viruses like CryptoLuck are not going anywhere any times soon. Thus, you need to learn how to effectively protect your system from any potential infections. Here are a couple of important guidelines to help you improve your system’s security.

  • Be mindful of what sites you visit while using your browser. The internet is filled with all sorts of malicious pages and illegal websites that can land you harmful malware if you are not careful. Therefore, avoid anything that seems shady and potentially harmful. Also, remember to download stuff only from sources that are verified and trustworthy.
  • Backup any data that is important for you. Even in the case of a Ransomware attack, if you still have accessible copies of your files, the infection won’t be a problem.
  • Meticulously double-check new e-mails and do not open ones that seem shady. In some cases malicious junk mail might come from people that you know if their computer had been attacked by hackers.
  • Get high-quality security software. Some anti-virus companies try to introduce Ransomware detection features. Also, oftentimes malware such as CryptoLuck gets distributed via other backdoor viruses – a good security tool would prevent any backdoors from getting onto your PC.
