Files from your flash drive can go missing if you have not checked “View Hidden Files” from the view tab. They can also be lost, if they are automatically moved by a third-party application or when infected with a virus. These files eventually can be found or restored to its original location. However, it is not the same case with the files that have been deleted without you noticing. They might have been deleted due to corruption or virus that was or is present on your flash drive.
Do Files Actually Get Deleted After Encountering Virus?
There are 3 common types of virus named as Worm, Trojan and Adware. Each virus has its own way of spreading or affecting your flash drives. So, coming back to the question
“Do files actually get deleted after encountering virus?”
The answer is yes as well as no because, Trojan and Adware virus make your files go corrupt but can still be accessed so that when these files are executed, they spread and damage more files. But the Worm virus is a self-replicating virus that modifies system data and deletes files from computer, connected networks and even external devices like flash drives, memory cards, etc. However, files that have been affected by Worm virus can be recovered using yodot file recovery software that can help you to recover deleted files from flash drive.
Let’s get to know how these common viruses spread on your flash drive or computer and how dangerous they are.
This malware tends to expose users to unwanted and malicious advertisements. Adware infects the user’s browser or applications and shows advertisements after each and every click they make. Some Adware’s also redirect you to malicious sites that have spammy ads all over the page or even install plugins automatically that infects your whole computer. Mail.ru is one of the common Adware that users usually get infected with. Removing this malware is as easy as removing the corresponding executable file. However, locating the specific executable file is tricky. Fortunately, this malware does not modify or delete the existing data.
User’s get exposed to Trojan majorly through random mails or suspicious applications. Trojan malware only works when somebody executes the file or application and this is the most common virus found in flash drives or a computer. A user may get a pop-up stating that “Your system is filled with virus, please scan now to remove the virus” and the user take the bait. Since majority of the computers have Anti-virus installed, this makes the Trojan virus look as a genuine pop-up notification that was sent by their Anti-virus itself.
Worm is a malware that deletes or modifies files on the host system. They are known for destroying connected infrastructures, networks and systems. As the malware name states, worm malware infects one file like a worm and those infected files spread more and affect the host system or systems connected within network. Recovering files from a flash drive or system that is infected with worm malware is possible but the recovered files might still have the Worm malware in it. This process will reoccur and spread the Worm malware within the operating system and networks as well. The Morris Worm which was the most popular malware around 1990s, infected large number of computers, external drives and then on internet too. The U.S Court of Appeal estimated that it could cost up to $53,000 to remove the virus from each of the affected drive or systems.
- Shortcut Virus:
Majority of the Flash drives are exposed to the “Shortcut Virus”. This virus hides the original files or application and replaces them with an infected shortcut of that file or application. Shortcut virus can be removed quickly from your flash drive by running command prompt and following the steps mentioned below.
Step 1: Use Windows+R to open Run, type CMD and hit enter
Step 2: Copy paste this attrib g:*.* /d /s -h -r -s (Replace “g:” with the letter assigned for your flash drive)
Step 3: Hit enter and the command prompt will remove the shortcut virus from your flash drive
