How do viruses typically spread through flash drives?
Viruses spread by being copied onto a flash drive from an infected computer. When you use that flash drive on another computer, the virus can infect the new computer.
What is the auto-run feature on flash drives, and how does it work?
The auto-run feature makes certain programs or files on a flash drive run automatically when you plug it into a computer.
Why is the auto-run feature considered a security risk?
Auto-run is risky because it can automatically start viruses on your computer without you knowing, which can quickly spread the infection.
How can disabling the auto-run feature help prevent the spread of viruses?
Disabling auto-run stops programs from starting automatically when you plug in a flash drive. This gives you a chance to check the drive for viruses before opening any files.
