Ransomware has become a popular tool for cyber criminals today. Crooks extort more and more money from companies and ordinary users with the help of extortion viruses. Home users can pay hundreds of dollar for the unblocking of their personal files, and business owners may pay thousands.
This post is intended to help you protect your data from ransomware.
Among all the initial protections, the first place should take your antivirus. Virus databases are systematically updated without user intervention. Antivirus developers regularly add new modules to protect your mail box from spam, and you web surfing activates from visiting fraudulent websites.
Updating the operating system and other software
Attackers often use various software vulnerabilities in the hope that users have not had time to install the latest updates. Most often it concerns the Windows operating system. You should check and, if necessary, activate automatic updates of the OS. To choose how to download and install updates go to Start > Settings > Update & Security > Windows Update.
Disabling the Encryption Service
Windows provides a special data encryption service; If you do not use it regularly, it is better to turn it off – some new ransomware viruses can use this function for their own purposes. To disable the encryption service, you must perform the following actions. Bring up the Run window by holding the Windows Key and press R. Type “fsutil behavior set disableencryption 1” in the window and press Enter.
Limited use of programs
To increase security, you can block the launch of any programs that do not meet special requirements. Got to Security Settings > Application Control Policies > AppLocker > Configure rule enforcement. Effective tuning may take some time, but the result is definitely worth it.
Using a standard user account
Working with an administrator account is not recommended even for advanced users. Restricting the rights of the account will minimize the damage in case of accidental infection.
To perform actions with administrative rights in Windows, a special tool is provided – User Account Control, which will ask for a password for performing an operation. You can check the settings here: Start > Control Panel > User Accounts > Change User Account Control Settings.
System restore points
Sometimes, viruses still manage to beat all levels of protection. In this case, you should be able to roll back to the early state of the system. To configure this feature, go to Start, type Create a restore point. In the System Properties window click System Protection > Configure select Turn on system protection.
To restore files on disc D using standard tools or the Shadow Explorer program, you must enable protection for all disks. The control points will take up some memory, but they can save your data in case of infection.
I strongly recommend that you regularly make backup copies of the most important information. This measure will not only help protect against viruses but will also provide insurance in case the hard drive fails. Be sure to make copies of the data and save them on external media or in cloud storage. It is desirable to have backup copies. After all, ransomware becomes meaningless if you can restore your files from backups.
I hope the guide will be useful for you and help protect the personal data (and money) from intruders.
