CryptoLocker Virus


CryptoLocker falls under the category of Ransomware viruses and is able to lock your files by using a sophisticated encryption and later demand a ransom payment for the decryption key. Information will be given to you concerning how CryptoLocker Virus operates and what can be done in order to prevent it from infecting your PC.

The article that you are currently about to read is focused on a malicious virus called CryptoLocker Virus . If it is too late for you and the nasty Ransomware has already invaded your system and locked your data, we might be able to help you restore your access to your files and remove the malware with our CryptoLocker Virus removal guide that can be found at the bottom of this article. However, we ought to tell you that there isn’t one hundred percent certainty that our guide will solve everything. This is because viruses of this type are getting more and more advanced at a very rapid pace and the methods that might have worked up until this point, might now prove to be ineffective. Still, we believe that it is much safer and much more sensible to use our guide in an attempt to solve your issue with the Ransomware instead of agreeing to paying the ransom. After all, who is to say that even if you send the money to the hacker you will actually be given the decryption key and not simply wasting your money for nothing?

Antiviruses oftentimes cannot detect Ransomware

If you have already had your machine attacked by the malicious software, you’ve most likely realized that your antivirus turned out to be utterly ineffective against the Ransomware. The reason for that is within the method that is used by those viruses while locking your data. As was already mentioned, the method that is employed is called encryption. What should be mentioned about encryption is that it is actually not a malicious type of process on its own. When used normally, it is actually very useful for high level data protection. This is also why most antiviruses do not alarm you when an encryption process is being carried out on your PC and neither do they interrupt the said process. However, obviously, when Ransomware is running the encryption, it is certainly not something you want since when the process is over, you won’t be able to open any of your personal files.

Be vigilant!

Generally, it is always a good idea to be observant of your machine’s behavior. It is even more so when you think that it might have been attacked by some harmful malware such as CryptoLocker Virus for example. Even though Ransomware viruses are indeed very difficult to notice, they might still show certain typical symptoms that might help you detect the infection. For example, if Ransomware is currently encrypting your files, it is likely that your machine will experience significant CPU and RAM spikes (in other words, unusually increased system resources consumption). Also, another very typical symptom is the decreased free storage space on your PC. The reason for this is because when your files get encrypted, they must first be copied. The copies are the ones that are actually locked by the encryption. During this time, you can notice the decrease of free HDD space. However, before the process finishes, the original files are deleted so that in the end you are only left with the locked copies.

Protection against Ransomware

Many users underestimate the importance of keeping their PC safe and well protected. However, if you want to make sure that no more Ransomware viruses are getting onto your machine, you must make sure that from now on you are doing everything you can, in order to ensure the security of your machine. To help you with that, we have prepared several useful tips and guidelines that, when used in combination with one another, will greatly improve your system’s security levels.

  • Be responsible when surfing the internet. If you are not careful with the websites you visit, you might end up on some shady, illegal page that might potentially infect your PC with all sorts of malware.
  • In order to prevent anything shady from getting downloaded on your PC, be sure to disable the automatic download setting on all of your browsers. That way, your permission will always be required prior to anything getting downloaded.
  • Internet spam is an extremely common method of spreading all types of undesirable and harmful software so always be careful when checking your inbox. Never click on links or open file attachments if you cannot be sure that they are safe.
  • Having a reliable antivirus program is a must! Even if it fails to spot a Ransomware infection, it could still prevent your PC from getting infected by backdoor viruses, which are commonly used for providing free passage for Ransomware into the users’ computers.
  • Last but not least, always make sure that your valuable data is backed up. When it comes to Ransomware, this is the one best way to counteract it. Also, even if you haven’t backed up something, if you think that your machine is attacked by this type of virus, do not connect the backup device to the PC, because it might get infected as well.
