How to Protect your USB Flash Drive from Viruses?

Nowadays, USB flash drives are the primary source for transferring or carrying data. We regularly connect our USB flash drive to many computers, but not all are virus free. Not to mention, viruses can spread to your USB drive while being connected to an infected PC. This will pose a threat to every other computer in which the drive gets plugged in thereafter including yours.

To keep away from these situations or to rectify a flash drive infected with the virus, you can try one of the solutions I’ve listed below. These solutions are easy, need some tools and a little amount of the internet.

Method 1: Keep your flash drive safe

You don’t need to download any tool to protect your USB drive, you have to edit the permissions of your flash drive (with NTFS file system), so the virus can’t infect your flash drive.

Steps:

  1. Right, click on the start button (or press Win+X) and open “Device Manager.”
  2. In device manager, expand the “Disk Drives” > right-click on your flash drive and click Properties.”
  3. In the properties window, select the “Policies” tab and select “Better performance” and click on OK.
  4. Now again format your flash drive using the NTFS file system.
  5. After format completes, open flash drive’s properties.
  6. Select the “Security” tab and set “Read-only” permission for everyone.

Now your flash drive is very much secure, and no virus can get transferred to your flash drive and infect it.

Method 2: Use USB Immunizer (Free | Windows):
