The file in my card cannot be read cuz it is

the virus coders just can't leave anything unscrewed up, can they!!? the virus could have been an 'undocumented' feature on your card, when you obtained it- such as some digital picture frames had. otherwise, it may be very difficult or impossible to clear it. unless there's some really important data on your card- trash it!! try contacting your cell phone provider, or service provider- on the net, or land-line phone, and see if they have an 'anti-virus' service that will 'kill' the virus! don't really have the knowledge- beyond laptops & pcs- but logic works, sometimes!!
good luck!!
