For data transfer we use pen drive, External Hard Disk or sometimes Memory card. We know that, not every person has antivirus. Also most colleges don’t use antivirus. Generally we Format Our USB after found virus. I don’t think that, this is right solution. Formatting a device can reduce efficiency of it.
How a Virus Can Effect any Device?
Typically, when we insert any USB to any device there is a malicious script. script is waiting for any device to execute the algorithm. After Execution, That script executes on drive letter like E, F, and G.
Some Script infect the USB by following:
- Putting Sexy Girl’s Photo
- Making Short-cut of all folder in it
- Making current drive short-cut on it
- Convert all folder to .exe extension
How To Make Virus Proof USB?
All script use Local Access level to execute particular code. If we disable the Local Level use to Administrator Level than we can stop any script from being execute. To do it practically, just go through the following steps:
- Insert any USB device and format it using NTFS file format
- Make new folder inside the Device and name it any thing
- Go to properties of that device
- Click on Security tab
- Click On Edit
- Deselect all check boxes but remain checked to “Read & execute”, “List folder contents” and “Read”
- Click Apply and OK on both windows
- Go to inside the USB and Go to Properties of the folder we’ve just made before
- Click On Security Tab
- Click On Edit
- Click On Full control
- Apply and OK to Both Windows as before
Bravo, you have just made your Storage Device Virus Proof. You can use this technique to your hard Drive also.
Now, you don’t have permission to Copy data to that device directly. so for that you have to use the folder virus proof to copy the data. And due to the permission your copy speed will be reduce but little. The main disadvantage is Windows XP can’t Detect the USB.
