Skull ransomware ransomware virus

This article is dedicated to Skull ransomware ransomware that gets into customers' machines around the world, and corrupts their data. Here we've compiled full information on what is Skull ransomware, and how to uninstall Skull ransomware from your computer. Furthermore, we'll explain how to restore the encrypted files and is it possible.

Skull ransomware is the perilous program infecting laptops mainly through e-mail spam and Trojans. Also, scammers use exploits to penetrate the computer, but they are quickly corrected. When infection is done, the virus checks the computer memory to find the folders for encryption and their general price. Currently, any modern ransomware can encrypt audio, text, image and video info in all known extensions. Extra attention is paid to business information, since representatives of business are the key target for fraudsters. All programs in the system will be safe since scammers are interested only in information. The process is executed through world-known RSA and AES algorithms, and it is so complex that that decryption of data without a key is impossible. Such complexity gives reason for such an incredible success of this sort of viruses in recent years: an ordinary customer, even having a pretty high experience in suchlike things, will never restore the data, and will have to pay ransom. The single manner to decrypt files is to hack the scammer's webpage and retrieve the encryption keys. Sometimes it is possible to withdraw encryption keys due to flaws in viruse's program code.

The knowledge of computers is quite significant in our century, because it assists customer to protect the PC from computer viruses. For encrypting viruses this is very relevant, because, unlike regular viruses, when you remove ransomware from the computer, the fruits of its doings do not vanish anywhere. To defend yourself, you have to understand these three simple rules:

    • Attentively inspect your emails, particularly the messages that have files attached to them. The most effective pattern of fraud messages is the notification about prize gaining or package receiving. You also should keep an eye on business correspondence, particularly if you don't know the sender and not sure what's inside. It is natural to be interested and click on the message even if it might be not for you, but don't forget that a single click on the attached file may cost you lots of time, money and efforts.
    • Heed to the pop-up windows. The most efficient manner of information recovery is the restoration via Shadow Copies, and Web-criminals have included the deletion of shadow copies in the basic functionality of malware. Anyway, deletion of shadow copies requires administrator rights and operator's confirmation. If you'll stop for few seconds before verifying the pop-up, it can save your files and your efforts.
    • Monitor the status of your machine. It takes a big part of hardware power to encode the information. In few minutes of infection, the CPU performance decreases, and the encrypting process emerges in Process Manager. You may anticipate this event and shut down the machine before information will be totally damaged. This, if the laptop is really infected, will protect a lot of your files.

You should know that deleting ransomware is just a, first move, which is required for the normal operation of the workstation. To recover the information you'll have to follow the instructions in the next part of our article. In case of ransomware we don't give the manual uninstall guide, because its complexity and the likeliness of faults will be too high for average customer. We don't recommend trying to delete the virus in manual mode, because it has many security mechanisms that will counteract you. The most common viral defensive technique is the deletion of data in case of data restoration or malware removal attempt. To avoid this, abide to the tips under this paragraph.
