Usb Immunizer is a compact Windows utility that protects removable media by blocking autorun.inf files and preventing automatic execution from USB drives. It provides a lightweight, focused defense against one common infection vector, helping to stop malware from spreading when drives are shared between machines. The tool is easy to run and designed to be nonintrusive, so it won’t interfere with regular system performance. On Windows, use the utility to immunize individual flash drives, external disks, or entire folders; the process writes simple protective markers that stop autorun-based exploits. It complements existing antivirus and endpoint protections by addressing autorun specifically, making it especially useful for IT staff, technicians, and frequent USB users. For Android devices with OTG support, some read-only protections may offer limited benefit, but the primary feature set targets Windows systems. If you encounter a usb immunizer error, check drive permissions, confirm the device is not write-protected, and verify the filesystem integrity before retrying. For a secure usb immunizer download, obtain the utility from reputable Windows software sources and follow the included steps; safe ejection after processing helps preserve the protective state. Troubleshooting guidance and simple install notes make it straightforward to add this extra layer of protection to your removable media workflow.

USB Immunizer works well! It does its job, and I feel more secure using my USB drives. The only downside is it can lag a bit during scans. I’d give it a solid 4 stars though—just needs some minor tweaks!
