Check whether the current computer is immune to WannaCry ransomware attack:
The effect of successful immunity is as follows:
We know that it is basically impossible to decrypt data files that have been encrypted without obtaining the key. But after understanding the principle of virus encryption, I found that there is still a certain chance to retrieve the original file: when the virus encrypts the original file, it will delete the original file. As long as the hard disk of the simply deleted file does not perform a large number of writing operations, there is a chance of successful recovery. possible.
Retrieve documents before damage:
1. Select deleted file recovery
2. Select the scan object: In the interface, select the disk or folder where the file was located before it was lost, and then click "Start Scan".
3. Scanning process: The greater the number of files, the longer the scanning time will be, please wait patiently. (General scanning speed is 3G in 2 minutes)
4. Preview of scanned results: Click on the file to preview, and those that can be previewed have a chance of being successfully recovered. Check the files (folders) that need to be recovered and click Start Recovery to recover the files.
5. Select the recovery path: The recovered files will be saved in the folder path of your choice, please select which folder you want to restore to. (It is strongly recommended to save the files to be recovered to another hard drive instead of the hard drive where the files were lost to avoid secondary damage)
6. View the recovery results: The recovered folder will be saved in the folder path you selected. Open the directory to check the recovered files.
The following situations require attention:
1. Scanned photos and office documents are not previewable and cannot be restored. (The office document cannot be previewed, indicating that the document is partially damaged).
2. The previewed file types are not supported. You can only know whether they can be used normally after restoring them.
3. Use the accidentally deleted file function. After scanning, the recovery probability of each file will be displayed. The higher the recovery probability, the higher the recovery success rate.
4. Video files are extremely prone to fragmentation and data overwriting, so the possibility of complete recovery of video files is very low.
5. Physically damaged hard disk or other storage media, the recovered files may be damaged files.
