Can You Recover Files from Virus Infected USB?

Have you ever encountered an onslaught of unknown viruses targeting your system? If you have undergone such an unfortunate experience, you are likely aware of the unexpected data loss that can result on hard drives, external drives, memory cards, and USB pen drives due to virus attacks. For individuals unfamiliar with the recovery process of virus-infected files from USB drives, this situation can be incredibly distressing.

However, there's no need to panic! On this page, we will introduce 3 potential solutions to find lost files on USB.

An Overview of Common Virus Types

What are the reasons behind USB drives falling victim to virus infections? The infection of a pen drive typically occurs when a user connects it to a PC that has already been compromised by a virus. Another possible scenario involves the introduction of virus code to the connected drive. This situation arises when a user visits infected websites and downloads files while the pen drive is still connected.

With the AV-TEST Institute reporting the creation of over 350,000 new malware variants on a daily basis, it is practically impossible to provide an exhaustive description of each and every potential malware that one might encounter. Instead, we will focus our attention on the most significant virus classifications and their potential to induce data loss.

  • File-Infecting Viruses: This category of viruses primarily targets executable files, such as those with .exe or .com extensions. Infected executables can render your operating system unstable, leading to disruptive error messages that hinder your workflow. In severe cases, file-infecting viruses can render the entire storage device inaccessible, preventing any access to previously stored files.
  • Macro Viruses: This type of virus is commonly found in Office documents, particularly those created using Word or Excel. Many Office documents support Visual Basic code, which allows cybercriminals to conceal viruses within them. When an infected document is opened, the hidden virus gains access to other parts of the system.
  • Web Scripting Viruses: Web scripting viruses are directly installed from the internet when a user visits a malicious website or downloads an infected file. Such viruses can upload your data to a remote server and subsequently delete it, causing even greater damage.
  • Boot Sector Viruses: Boot sector viruses are directly written to the boot sector, enabling them to execute each time the infected computer starts up. Due to the nature of this virus class, which often blocks access to the operating system, recovering lost files becomes slightly more complex, though not impossible.
