remove virus from flash without pc

When i say Flash,what i mean is memory card.Using it as a flash.
It is very easy for virus to spread from one pc to another through infected flash,memory card etc.
A simple way to effectively check the spread of virus is to use memory card as your flash.
It is also important to have a device that can access the information in you memory card.I dont know of any device apart from computer that can access flash.So,i use memory card along with my card reader to copy,save and transfer files from one pc to another.
Your device, (phone,ipod etc) and not a pc will be used to access the memory card as virus for pc cannot harm your phone.In my case,i use N70 with file manager like file explorer and x-plore installed.
After ejecting the memory card from the pc,i put it in my phone and us x-plore to check the memory card for virus.If i detect a virus in the memory card,i just delete it.With this method,i've cleaned my memory card.Funny scandal,chinese autorun,new folder etc can be removed easily!
