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?
