I have installed win xp pro and then service pack 1a and then sp3 (SPs are not integrated). I have eset smart security. It detected that I had a worm in my computer named: Win32/Conficker. I somehow got rid of that worm and now my system is reported as clean. But One thing which I am unable to do still is to be able to see hidden files. Every time I select all the files, I get a message that some files are hidden. And every time I change the hidden files setting in Folder Options and whenever I open the Folder Options, the hidden files setting disabled. It appears as if the Folder Options setting never changes. Please help.
