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 gives 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.

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]]

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 input of the command line is suitable for computer professionals since wrong commands can cause more severe problems. Therefore, for security and usability, we strongly recommend you try an automatic command line alternative.

3 Other Ways to Remove Virus

In addition to using CMD, there are other methods available to remove a virus from your computer or storage device, like using antivirus software, Windows Defender, and formatting the storage device.

Method 1. Run Antivirus

Almost every computer has antivirus software installed. Whenever you find your computer is infected by a virus, running the antivirus software may help.

Method 2. Run Windows Defender Antivirus

Windows Defender Antivirus is the built-in antivirus protection in Windows 10. It provides protection against viruses, malware, and spyware for your computer and connected devices. If you don't have third-party antivirus software, using the built-in utility is advisable.

Step 1. Go to "Settings" > "Update & Security" > "Windows Security".

Step 2. Click "Virus & threat protection".

Step 3. In the "Threat history" section, click "Scan now" to scan for viruses on your computer.

Method 3. Format the Infected Device

The format is the process of erasing the existing files on the selected partition or drive. It will certainly remove the virus, too. Since formatting a partition/drive will cause data loss, make sure you don't have any important files stored on the device.

How to Recover Files Deleted/Hidden by Viruses

Don't forget to use a data recovery tool in case the virus deleted or hid your important files on USB and other drives. Using commands can only help remove the virus but can do nothing to restore damaged and lost files. EaseUS file recovery software is able to complete virus file recovery in just three steps.
