I sometimes use my android phone (Nexus 4, Avast free antivirus) as a flash drive for transferring various types of files between PCs. I oftentimes connect it to my laptop for charging.

 

Recently, one of my PCs was exposed to a worm that spreads via flash drives, making me realize my phone is a potential malware vector.

 

I understand disabling autorun.inf is one aspect of securing a flash drive. Can that be performed on my phone?

 

Any other suggestions?

Although this doesn't address the matter of disabling autorun.inf, you can check if your phone's storage is infected using a file explorer (such as ES File Explorer, from Play store). If there's an autorun.inf, you should see it.

Thanks inactivecores!

 

I looked for autorun.inf on my Nexus 4 using the search function in "ES File Explorer" and didn't find an autorun.inf file.

 

Do you have any suggestions for permanently disabling autorun.inf on Android phones?

I'm not sure if it is recommended to use this tool but there is the Panda USB Vaccine.
