HC6 ransomware virus

 

HC6 is the undesired program penetrating computers mainly with help of e-mail spam and Trojans. Sometimes web-criminals use zero-day vulnerabilities to take control over the system, but big software developers quickly fix them. When infection is done, HC6 reviews the hard disc, defines the quantity of files for encryption and their general value. Currently, each modern ransomware knows how to cypher image, text, video and audio files in all popular extensions. High attention is attracted to businesslike files, because medium and large companies are the priority target for fraudsters. All software in the system will be unaffected since hackers are interested only in information. Encryption is made through famous RSA and AES algorithms, and it is so complex that that decipherment of files without a key is impossible. Such complexity gives foundation for unbelievable effectuality of ransomware in recent years: usual PC operator, even having a fairly high experience in suchlike things, won't ever restore the data, and will have no choice except paying the ransom. The only manner to decrypt files is to crack the fraudster's website and retrieve the master key. Some experienced malware specialists can retrieve encryption keys due to faults in the code of the virus itself.

 

There is one common feature for all types of computer viruses: it is way simpler to prevent it than to cure it. Statistically, 90% of customers realize the significance of PC literacy just when ransomware takes over their workstations. It's very easy to reduce the chances of getting encrypting virus by following these rules:

 

    • Don't admit any alterations to the system, coming from weird programs. If the computer is penetrated by virus, it will endeavour to delete the shadow copies of the files, to decrease the chances of recovery. However deleting of shadow copies needs admin rights and confirmation from the operator. If you'll think for few seconds before verifying the changes, it might save your files and your time.
    • Don't ignore the symptoms that your laptop displays. Information encryption is a sophisticated operation that needs a significant amount of computer resources. If you mention a significant fall in computer capacity or detect a strange process in the Process Manager, you can shut down the workstation, load it in safe mode, and search for viruses. Naturally, some files will be encrypted, but the other part of them will remain intact.
    • Attentively examine your emails, specifically those messages that have attached files. The #1 model of scam messages is the notification about prize gaining or package obtaining. The second very common kind of scam letters is a "business messages". It is normal to be interested and open the letter even if it might be not for you, but don't forget that a single click on the attached file might cost you a lot of money, headache and time.

Virus uninstalling isn't the happy end - it's just a first move in the long road before the complete file restoration. If you remove HC6, you will not get back the data immediately, it will need multiple measures described in the "How to restore encrypted files" part. To get rid of HC6, user has to start the PC in safe mode and run the scanning via antivirus. We don't advise anyone to delete the virus by hand, because it has various protection mechanisms that could counteract you. Some ransomware are able to fully delete encrypted information, or part of it, if user tries to uninstall the virus. To neutralize this, abide to the instructions below.
