Introduction

Did you know that USB flash drives can be silent carriers of viruses? 🦠 Just like an unsuspecting handshake with someone sick, plugging in an infected USB can introduce malware into your PC in seconds. Scary, right?

One of the most notorious threats is the Autorun USB Virus, a sneaky malware that spreads automatically when a USB is plugged in. If you’ve ever experienced mysterious files appearing or your PC acting strangely after inserting a USB, you might have met this digital troublemaker.

USB-based malware isn’t the only risk—similar threats can come from malicious charging cables. Many cyber criminals use modified USB charging cords to inject malware into unsuspecting devices. Learn more about the dangers of using unknown charging cables and how to stay safe.

1. Understanding the Autorun USB Virus

What is an Autorun USB Virus?

The Autorun.inf virus is a self-executing malware that activates as soon as you insert an infected USB into your PC. It exploits the autorun feature in Windows, making it easy for viruses to spread without your permission.

Many other types of computer viruses work similarly, and it’s important to know how they operate to protect your system effectively.

How Does USB Malware Spread?

• Plug and infect: As soon as a USB is inserted, the virus automatically runs.
• File disguise: It creates fake folders or shortcuts that trick you into clicking on them.
• Hidden files: It hides malicious files inside the USB, making them hard to detect.
• Network spreading: Once in your PC, it can spread to other devices on the same network.

Signs Your PC is Infected 🚨

• USB files turn into shortcuts.
• Your PC runs slower than a snail. 🐌
• Strange pop-ups or errors appear.
• You can’t open files on your USB.
• Antivirus software keeps detecting threats.

If any of these sound familiar, your PC might have a USB autorun virus!
