How to Repair Virus Infected Video Files

Proven Ways You Can Repair Virus-Infected Video Files

If you’ve been one of the unlucky few to experience a virus infection on your computer, you know about the havoc these malicious apps can wreak and the damage they can cause to your files. Seeing corrupted and infected files can be devastating, even more so if the virus infects your precious video memories.

That’s why today, we’ll dive deeper into viruses, their types, and what they do. Moreover, we’ll show you how to repair virus-infected video files with three different methods and teach you how to prevent future infections.

How Computer Viruses Work

Computer viruses are malicious applications that have been infecting computers since the 1970s. These programs often replicate themselves to cause maximum damage and spread on external devices or networks, hijacking files, attaching themselves to other apps, and stealing sensitive data.

More often than not, these malicious apps infect your PC by appearing like genuine apps or trustworthy emails and links. From there on, they spread like wildfire, infecting what they can, slowing computers down, and causing OS damage. Some viruses may also nest themselves and hide, awaiting instructions.

Types of Computer Viruses and What They Do

Now that we know what viruses are and how they work, we can dive deeper into the most common types and how they wreak havoc on your PC. Below is a list of the nine categories of computer viruses.

  • File Infector – When you think of a computer virus spreading, you’re likely imagining a file infector, which injects malicious code into vital operating system files and other data like videos;
  • Boot Sector Virus (Rootkit) – Arguably the most violent virus type and often spread through USBs, rootkits nest in your PC’s boot sector, rendering your computer unusable once activated;
  • Browser Hijacker – Using your web browser, this virus type changes your settings and URL, navigating you to phishing websites and stealing your data;
  • Direct Action Virus – It’s likely the type of virus you think of, as it represents an executable file (.exe) that you double-click, and it infects your PC;
  • Resident Virus – This type of malware sits in your memory and waits for further instructions from whoever infected your PC;
  • Web Scripts – Such programs penetrate the web browser’s defenses, allowing bad players to run code on your device;
  • Polymorphic Virus – As the name suggests, these viruses use polymorphic code, which constantly changes, allowing them to stay undetected;
  • Macro Virus – This tiny malware type uses Microsoft Office macros to download additional infections and wreak havoc;
  • Multipartite Virus – Such viruses copy themselves to spread over the network and inject malicious code into critical files.

Although these are the nine most common types of viruses, other types may also exist as hackers are constantly upping their game and evolving viruses. Luckily, most of these are removable.

It’s worth noting that Wondershare Repairit also has an online version, which functions similarly to the desktop app. The differences between the desktop app and the online service exist, like the number of supported video formats, file size limit, and the number of videos you can repair each month when using the Online Video Repair tool.

However, the online version is still terrific at what it does, so let’s see it in action.

Repair Virus-Infected Video Files Online

If you want to avoid downloading applications, Repairit’s Online Video Repair tool is the perfect option, and you can quickly access it on any device with a web browser. Using it is as simple as the desktop app and only requires three simple steps. We’ve also included step-by-step instructions for your convenience:

Step 1: Open a web browser and navigate to the Wondershare Repairit Online Video Repair.

Step 2: Click the Add button to upload virus-infected videos.

Step 5: If you’re happy with how the video turned out, click the Download All button to save the repaired files to a safe location.

Apart from the three differences mentioned above, the Repairit Desktop app and the Repairit Online Video Repair service are similar. Both are excellent at dealing with virus infections and repairing infected videos, and both tools use the same repair process and algorithms and require identical steps.

Using VLC to Repair Virus-Infected Video Files

While primarily a tremendous media player, VLC is also an excellent tool for fixing video errors, and it can even repair virus-infected video files. The app’s Convert / Save feature allows users to convert video files from one format to another, fixing issues and eliminating viruses in the conversion process.

Although you shouldn’t expect miracles from it, VLC is undoubtedly worth trying. The app is entirely free since it’s open-source, making it a viable option to repair virus-infected video files on a budget. Here’s how you can try it:

Step 1: Launch VLC, and go into Tools > Preferences.

Step 2: Navigate to the Input / Codecs tab and select the Always fix option from the dropdown menu next to the Damaged or incomplete AVI file.

Step 3: Hit Save, tap the Media button, and click Convert / Save.

Step 6: Specify where to save the converted files by clicking Browse under Destination and then clicking Start.

Once converted, your virus-infected video files should be virus-free now. However, it’s worth noting that the VLC media player isn’t a dedicated video repair tool. While it can handle minor issues, errors, and infections, it won’t always be successful.

How to Prevent Future Virus Infections

After eliminating the threat and repairing virus-infected video files, you’ll likely want to take some precautions and ensure the same doesn’t happen again. Therefore, we’ve included a few tips on protecting your PC and data and preventing future virus infections.

  • Protect your Wi-Fi network with a strong encryption and password;
  • Use different and secure passwords for apps and websites;
  • Regularly back up your vital data with UBackit;
  • Keep your operating system up to date;
  • Install and regularly update an antivirus software;
  • Don’t click on suspicious links or emails;
  • Carefully check the URLs you’re visiting.

Incorporating these tips into your daily computer usage will decrease your chances of infection by a significant margin. If they happen again, you know what to do and how to repair your files.


Viruses can cause chaos on your PC, and the infection can often spread on vital data. It’s even more frustrating when a virus infects your video files and precious memories and causes corruption.

You shouldn’t immediately go into deletion mode, though, as there are dedicated repair tools that can help. For example, the VLC media player can sometimes eliminate file corruption and repair virus-infected video files. However, it’s still a media player at its core and doesn’t do miracles.

Instead, you can use a dedicated video repair tool like Wondershare Repairit, which is highly recommended since it was created for it, and we’ve shown you how to use both the Desktop and the Online Repair versions.
