Can a cell phone be infected with a virus when you download an e-book from your computer to your cell phone?

If your computer is infected with a virus or if you download a web page with a virus, the virus will be transmitted to your cell phone.

But a virus on your cell phone won't affect the normal use of your cell phone, that is, it won't affect your ability to make or receive calls or send or receive text messages.

But it does affect the use of your cell phone's USB flash drive. You can see a lot of inexplicable files in your phone's file management that take up space on your phone.
