How to remove Walker virus and restore encrypted files

Walker ransomware virus

That item is about ransomware called Walker that gets into computers around the world, and cyphers their data. Here we've assembled complete info on what is Walker, and how to remove Walker from the laptop. In addition, we will explain how to get back the corrupted data and is it possible.

Walker ransomware had infected many laptops around the world with help of easiest method: fraud e-mails with dangerous attachments. Occasionally hackers use exploits to get into the system, but they are quickly corrected. After penetration, Walker scans the hard disc to find the folders for encryption and their general worth. Currently, any modern ransomware can cypher image, text, audio and video files in all most used extensions. Extra attention is paid to businesslike documents, since medium and large companies are the key objective for scammers. Walker targets only files with information, and doesn't affect the programs, so that the man can use his PC to make the payment. The operation is executed via famous encryption algorithms, and it is so complex that that decipherment of information with no key is impossible. This is the basis for such an incredible effectuality of ransomware in recent years: usual user, even having a fairly high experience in suchlike things, will never be able to recover the data, and will have no choice except paying to fraudsters. The sole manner to decrypt the information is to hack the scam site and obtain the encryption keys. Also there's a way to get encryption keys due to faults in viruse's program code.

The knowledge of computers is extremely substantial in our century, because it assists you to guard the computer from harmful programs. Statistically, 90% of users see the significance of computer literacy only after ransomware infection. You easily can minimize the chances of getting encrypting virus if you'll follow these principles:

    • Be cautious with the e-mails which contain files. The very efficient template of fraud messages is the story about prize gaining or package obtaining. Also you should keep an eye on business correspondence, particularly if you don't know the sender and not sure what's inside. summaries, Bills for services and products, lawsuits, appeals and suchlike sensitive files cannot be sent without warning, and the receiver should know the person who sent it. In most of the cases it is a fraud.
    • Don't disregard the red flags that your laptop shows. Data encryption is a sophisticated operation that consumes a lot of hardware resources. In the first minutes after the infection, the CPU speed decreases, and the encryption process can be seen in Process Manager. You can catch this moment and switch off the computer before files will be totally spoiled. Surely, the certain amount of data will be lost, but the rest of them will remain intact.
    • Don't accept any changes to the PC, coming from unknown programs. The easiest manner of information recovery is the recovery through Shadow Copies, and scammers have added the elimination of those copies in the default features of viruses. The deletion of shadow copies needs administrator rights and verification from the user. The second of thought before accepting the changes might save your information and your time.
