What Damage Could Viruses Do
We loathe computer viruses, undoubtedly. But do you know exactly how viruses can damage your computer? There are many types of viruses, and they behave in different ways. To sum it up, a computer virus is simply a type of program that causes your computer to act in an undesirable way. It can be a dangerous infiltration designed to drag your computer down, erase important files, track your habits, or give hackers access to your personal information... A virus is a great nuisance. Some viruses like the Locky virus and CryptoLocker, also known as ransomware, delete computer files, encrypt them, even change the file extension to .locky or .encypt. Other viruses hide files and leave users with nowhere to unhide them.
How to Recover Files Deleted/Hidden by Viruses
Using CMD commands can only help remove the virus but can do nothing to restore damaged and lost files for the virus infection. EaseUS Data Recovery Wizard can recover lost data in various severe cases.
EaseUS data recovery software
- Recover lost or deleted files due to virus attack
- Recover files from emptied Recycle Bin on Windows 10/11 or recover deleted files from Trash Bin on Mac
- Recover lost files from HDD, SSD, USB flash drive, pen drive, SD card, external hard drive, and more devices
- Support repairing corrupted files after the data recovery
Learn the 3-step file recovery in the following guides.
Step 1. Select the virus infected drive to scan
Run EaseUS virus file recovery software on your Windows PC. Select the disk attacked by the virus to scan for lost or hidden files. Note that:
- If it's an HDD where files were hidden or deleted by virus, it's better to install the software on a different volume or an external USB drive to avoid data overwriting.
- If the infected device is an external hard drive, flash drive or memory card, it doesn't matter to install the software on the local drive of the computer.
Step 2. Check all scanned results
EaseUS Data Recovery Wizard will immediately start a scan process to find your deleted or hidden files on the virus infected hard drive. To quickly locate the wanted files, you can use the Filter or type grouping feature to display only the pictures, videos, documents, emails, etc.
Step 3. Preview and recover deleted/hidden files
When the process finishes, you can preview the scanned files. Select the files you want and click the "Recover" button. You should save restored files to another secure location on your computer or storage device, not where they were lost.
It's certainly true that a virus is something you will want to remove once you find it. Among the multiple choices, many users attempt to remove viruses using CMD.
Why Can You Remove a Virus Using CMD
In fact, using command lines doesn't directly check and remove viruses from your computer or external storage device. CMD helps to achieve your goal of removing viruses by showing the hidden viruses on a partition or drive. Afterward, you can delete the suspicious files. Since viruses always conceal themselves, you need to make them appear and then delete the virus files. Then how can you show the potentially hidden virus files using CMD? All you need is the attrib command.
The attrib command is a Command Prompt command used to display, set, or remove the attributes of the files or folders in the selected location. By canceling the "hidden" attribute of the virus, you can see it appearing in the folder. And then you will know where to find and remove it.
How to Remove Virus Using CMD
Now, follow the steps below to delete viruses from your computer or storage device using CMD.
Step 1. Type cmd in the search bar, right-click "Command Prompt" and choose "Run as an administrator".
Step 2. Type F: and press "Enter". (Replace "F" with the drive letter of the infected partition or device.)
Step 3. Type attrib -s -h -r /s /d *.* and hit "Enter".
Step 4. Type dir and hit "Enter". Now you will see all the files under the assigned drive. (The dir command displays a list of a directory's files and subdirectories.)
Step 5. For your information, a virus name may contain words like "autorun" and with ".inf" as the extension. Thus, if you find such suspicious files, type del autorun.inf to remove the virus.
Here are the basic attributes of the 'attrib' command:
R – represents the "Read-only" attribute of a file or folder. Read-only means the file cannot be written on or executed.
H – the "Hidden" attribute.
A – stands for "Archiving" which prepares a file for archiving.
S – the "System" attribute changes the selected files or folders from user files into system files.
I - "not content indexed file" attribute.
The "attrib" Syntax:
ATTRIB [+ attribute | – attribute] [pathname] [/S [/D]]
In the above command, let's see what the different parameters and switches are:
'+ / –': To enact or to cancel the specified attribute.
'attribute': As explained above.
'/S': Searching throughout the entire path including subfolders.
'/D': Include any process folder.
'pathname': Path where the target file or folder is located.
Here is the proper syntax order for attrib command:
ATTRIB [+R | -R] [+A | -A ] [+S | -S] [+H | -H] [+I | -I] [drive:][path][filename] [/S [/D] [/L]]
- Be careful while using the Command Prompt. Improper use of cmd can result in system damage. So, perform data recovery in advance, and then continue with the CMD method.
If you receive the message "Access denied", you should:
- Make sure you have run Command Prompt as an administrator
- Make sure the file/folder is not in use
- Check the permission of the current account and make sure you have full control over the file/folder (right-click the file/folder/partition and go to "Security")
- Use CHKDSK command to check for file system errors (run Command prompt and enter chkdsk /f [drive letter]:)
Manual execution of the command line is suitable for computer professionals, since incorrect commands can do more harm than good. Therefore, for security and usability, we strongly recommend you try an automatic command line alternative - EaseUS CleanGenius. It is a practical tool that enables you to check and fix file system errors, enable/disable write protection and update your system with one-click instead of typing intricate command lines.
