While computerization is highly beneficial, it also comes with its flaws. One of these is the loss of data on a digital storage device. Such a situation can be caused by a virus or by mishandling a security program. Faced with a problem of this kind, you should try everything before resigning yourself to the idea that your data is completely lost. Here, then, is how to go about recovering your files.
Using data recovery software
Before trying to recover your data, it is essential to understand how your files become infected by viruses. Commonly known as “ransomware viruses”, these harmful digital elements infiltrate your computer’s system. Once inside, their purpose is to delete, hide, or encrypt your information. This is how access to hidden files becomes completely impossible.
To fix this problem, the type of software used must have a “data recovery” option to allow you to recover the infected files. There are many computer programs capable of such a feat. You simply need to download one of them and install it on the affected device. Its range of action extends from the main storage device to the infected peripherals. They just need to all be interconnected.
Once the software is ready to use, start it and launch a system scan. All encrypted elements will be examined, regardless of their location. Encrypted files will be listed so you can check whether they are still usable. Then select the data recovery location and start the process.
Once the operation is complete, the elements you have just recovered will be stored in the space you chose. They will be available again and fully reliable. Nevertheless, it would be wise to call on an IT professional. They will be able to properly carry out the procedure and identify the right data recovery software for the task.
Recovering a previous version of the infected files
This method also requires the use of decryption tools. Like shadow explorer, the way these programs work is similar. A few steps must be followed to achieve this. They are as follows:
- Find the location of the encrypted files;
- Open the item’s properties by right-clicking on it;
- Select the tab labeled “previous versions” and a list will appear;
- Choose the last known good version of the folder (the second-to-last one on the list);
- Check whether it is the right version by clicking “Show”;
- Recover the previous version found.
The final step requires three actions. When you find the recovered file, save it under a different name and in a new location. Then create a copy of this version in the same folder as the original item. To complete the process, choose the “restore” option to replace the damaged file.
Performing a system repair on the PC
This data recovery process is carried out on the computer’s entire internal storage. The operating system will undergo a full restoration. The advantage is that you will save time and the result will undoubtedly be positive. However, you will also lose files. In fact, your encrypted elements will be completely ejected from the device.
In general, the process for removing viruses is similar, but depending on the version of Windows (7, 8, 8.1, 10), the restoration may work a little differently. First, you need to find the control panel. It can be found under “Settings” or in the toolbar.
Once there, click on “Recovery“. You will come across another list of options where you will find “System Restore“. After selecting it, click “Next” to view the available system versions.
The purpose of this maneuver is to bring the system back to a state prior to the virus intrusion. Be careful not to reinstall a version that contains encrypted files. Once your choice is made, click “Finish“. After a restart, all encrypted elements will have disappeared.
Recovering your data from a backup
This method assumes that you have planned ahead with a backup of your data. This way, to retrieve the information, you simply need to copy it back over. However, there are prerequisites you need in order to successfully recover your data.
First, you must identify your encrypted elements. After that, set them aside from the other folders and delete them. Then go to your backup location and copy the previously deleted data. Finally, bring it back onto your PC.
It is important that the backup device cannot itself be affected by viruses. If it is, your elements will also become encrypted and recovering them would be pointless. It is therefore ideal for the backup to be kept isolated from your computer.
You can now recover your encrypted files using these tips. You can also install regularly updated antivirus software to avoid this type of problem. If you still can’t manage it, contact a professional.
