Virus on memory card

[Boki92]

I don't know if this is the correct place to post this, but here goes...

I have a virus on my memory card, and I've formatted so many times, and used an anti-virus (bitDefender), but it just keeps coming back! It's so annoying! I don't know what to do to get if off! Please help?:(

try reflashing the phone, it may help if virus is in internal memory
