Final answer:
To recover data from a virus-infected computer, you can run a full system scan using antivirus software, format the hard drive as a last resort, or restore from a backup if available.
Step-by-step explanation:
To recover data from a virus-infected computer, there are a few steps you can take. Running a full system scan using an antivirus software is a good starting point. This will help detect and remove any viruses or malware that may be present.
If the virus has caused significant damage to the computer or files, it may be necessary to format the hard drive. However, this should be considered as a last resort since it will erase all data on the drive.
If you have a backup of your data, restoring it from the backup is the safest option. Regularly backing up your important files is recommended to ensure their safety in case of any unforeseen issues.
