How to remove Scarab virus and restore encrypted files

Scarab ransomware virus

The page is dedicated to ransomware called Scarab that penetrates systems in different countries of the world, and encrypts the files. In this page we've compiled full information about what is Scarab, and the uninstalling of Scarab from your system. Furthermore, we'll explain how to get back the cyphered files, if possible.

Scarab ransomware had infected thousands of laptops in different parts of the world via easiest way: scam messages with dangerous attachments. Occasionally web-criminals use exploits to get into the system, but big software vendors promptly fix them. After penetration, Scarab examines the PC memory, defines the number of files to be encrypted and their general worth. At the moment, any new ransomware can cypher text, audio, video and image information in all popular formats. High attention is attracted to business information, because representatives of business are the priority target for fraudsters. All programs in the system will be safe because hackers want only information. Encryption is executed with the help of famous AES and RSA algorithms, and its complexity is so above the average level that it can't be bruteforced. Such complexity is the foundation for unbelievable effectuality of this kind of viruses in last years: common user, even having a pretty high experience in suchlike things, won't ever be able to decrypt the files, and will need to pay the price. The only method to decrypt files is to find the fraudster's site and get the encryption keys. Some experienced malware specialists can retrieve encryption keys due to defects in the code of the virus itself.

There is one thing in common between all kinds of ransomware: it is way easier to prevent it than to neutralize its fruits. For ransomware this is most relevant, since, in contradistinction to normal viruses, after removing ransomware from the system, the consequences of its actions won't vanish anywhere. You easily can reduce the chances to get ransomware by following these regulations:

    • Don't neglect the symptoms that your computer shows. File encryption is a complex operation that requires a considerable amount of system resources. If you notice a strange reduction in system power or see a unwanted process in the Process Manager, you can shut down the laptop, launch it in safe mode, and run the AV-tool. This, in case of infection, will protect a lot of your information.
    • Don't admit any alterations to the system, originating from strange software. If the computer is polluted by ransomware, it will endeavour to remove all copies of your data, to make the decryption less possible. However removal of copies requires administrator rights and user's verification. Thus, if you do not accept alterations from a unknown program at the proper moment, you will keep the opportunity to recover all lost data for free.
    • Closely examine your emails, particularly those messages that have attached files. If the letter comes from an unknown sender and it notifies about earning any prize, a lost parcel or something like that, this might be ransomware. You also should keep an eye on business-related letters, particularly if you don't know the man who send it and not sure what's inside. It is OK to take an interest and read the message even if it's sent to the improper address, but don't forget that one click on the viral file might cost you a lot of time, headache and money.

Virus deletion isn't the happy end - it's only a first step on the long road until the total data restoration. To get back the data you'll need to familiarize with the tips in the following chapter of our entry. To remove the malware, you need to load the computer at safe mode and scan it via antivirus. High grade ransomware can't be deleted even through antivirus-program, and have other effective mechanics of security. Qualitative viruses are able to fully delete corrupted data, or part of it, if user attempts to delete the virus. This is very bad, and the below guide will help you to avoid it.
