Hi. I can't see my hidden files. When I go to tools -> folder options -> view, checked "Show hidden files and folders " radio box, then Apply button and Ok. When I open the same window again it shows that "Show hidden files and folders"radio box is unchecked. I coluldn't check it anyway. Even I tried Start >> Run >> (type) regedit >> KEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced. find "Hidden" Rightclick it and modify it to 1. But the same problem.I know that I have virus in my computer, but my ativirus does't fint it. Please help me.
