Help SD Card Mounted as Read-Only when connecting to WiFi

[rotyron]

Hi. Please someone help me. I don't know if my mobile phone (HTC Wildfire) or my memory card is infected by a virus. Whenever I try go online through WiFi connection, my SD Card becomes Read-Only thus I can't use my mobile phone virtually, while online since I can't save or retrieve data from my memory card. And I noticed that my battery drains faster than it used to be even when I don't use it that much. My wildfire wasn't like this until a few months ago.
