How to remove Kodc virus and restore encrypted files

This item is about virus called Kodc which infects users computer's around the world, and encrypts the files. Here we've assembled complete information about Kodc's essence, and how to get rid of Kodc from your PC. In addition, we'll teach you how to restore the cyphered files and is it possible.

Kodc ransomware virus

Kodc is the dangerous software getting into PC's mostly via Trojans and scam e-mails. Also, hackers use exploits to penetrate the system, but they are promptly corrected. After penetration, ransomware checks the hard drive, defines the quantity of files to be cyphered and their rough price. Currently, each modern ransomware is able to encrypt text, audio, video and image information in all popular extensions. Ransomware cyphers all files, but the ones that might be business correspondence go first. Kodc encrypts only information, and doesn't spoil the programs, so that the victim can pay the ransom with help of his computer. Encryption is carried out through well-known AES and RSA algorithms, and it is so complex that that decryption of data with no key is impossible. This is the reason for impressive efficiency of this sort of viruses in recent years: usual customer, even having a very high knowledge of the computer, will never be able to get back the files, and will have no choice except paying the ransom. The sole method to recover files is to find the scammer's webpage and retrieve the encryption keys. Also there's a way to obtain these keys through flaws in viruse's program code.

The computer knowledge is extremely important in progressive world, as it helps user to defend the laptop from malicious programs. Unfortunately, most people understand the importance of PC literacy only when ransomware takes over their workstations. To protect yourself, you must keep in mind a three simple regulations:

    • Do not disregard the signs that your workstation shows. File encryption is a complicated act that needs a lot of computer resources. If you see a significant decrease in workstation performance or notice a strange process in the Process Manager, you need to shut down the machine, load it in safe mode, and scan for threats. This, if the PC is really infected, will protect a lot of your files.
    • Take notice to the pop-up windows. One of the most efficient ways of information recovery is the recovery from Shadow Copies, so Web-criminals have included the elimination of SC in the primary functionality of malware. The removal of shadow copies requires administrator rights and user's confirmation. Thus, not accepting changes from a weird software at the proper moment, you will reserve the chances to recover all corrupted files free of charge.
    • Be cautious with the e-mails that contain files. The most popular template of fraud e-mails is the notification about prize gaining or package receiving. The second very effective kind of scam messages is a "business letters". Invoices for services or products, reports, lawsuits, summaries and other important information don't come without warning, and you, as a minimum, should know the person who sent it. Otherwise, it is a scam.

You should understand that the deletion of the virus is just a first and compulsory turn for the standard work of the machine. If you get rid of ransomware, you will not recover the files immediately, it will require additional actions written down in the next paragraph. To uninstall Kodc, user needs to load the laptop in safe mode and run the scanning through antivirus software. We do not advise trying to delete the virus manually, because it has many defensive features which can interfere you. Qualitative viruses are able to fully remove encrypted information, or part of it, when trying to eliminate the program. This is extremely bad, and the following paragraph will help you to avoid it.
