I already have spybot and when i tried to open it, it didn't. As far as the hidden files and folders are concerned, i managed to find a tweak on the net. It was some registry editing and then i am able to see the hidden files/folders but i need to select that each time. Once i do it for a particular folder, and move to some other folder, it again hides the files.

Same thing happens with task manager and registry editor. I tried to enable the task manager and regitry editor through gpedit.msc and can do it for a moment after which the settings reverse back automatically.
