My R4DS accidentally have a virus, I notice it when I put my USB Transflash on my computer and my computer automatically scan my R4DS. It seems the virus only effects on my NDS category, so my _system_ and moonshl directory is infected by virus. Weird thing is, my NDS still work properly. Last time I delete that 2 categories and download kernel 1.11 and replace into the new one. When copy+paste the directories, there is command box that told me do you want to override it or not. I'm surprise and check again my R4DS and can't found any directories with it. I tried to use address menu on my computer and they found it. But still I can't found it on my R4DS without address menu on my computer. When I override my R4DS directories, it seems there are no change in my R4DS. The categories not shown (I already tried show all hidden files, but nothing happen) and that make me little bit stress. Can someone help me how to get rid this virus and restore my directories back? Thanks in advance.
