  1. I have follow this step, and i know the step is copied from a site. I had double-clicked the bat file, but the .txt file didn't appear like the instruction said. the autorun.inf folder had disappeared, but my antivirus still quarantine an activity that done by Flash_disinfector when it still there in my computer(before flash_disinfector deleted). Beacause of it, I'm getting assumption that the remove is not succeed. So, could u give me a suggestion about it?
