Do Files Actually Get Deleted After Encountering Virus?

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.
