This is normal,
unchecked every box (read only) on every file, on every folder on the drive only have it change right back
A quote from Microsoft
I have seen others with the same problem as you are having. The problem is with a file attribute (ie Read Only) being set. In XP Pro, the fix is straight forward, those were the steps I had you do before I new you were running XP Home.
Unlike the Read-only attribute for a file, the Read-only attribute for a folder is typically ignored by Windows, Windows components and accessories, and other programs. For example, you can delete, rename, and change a folder with the Read-only attribute by using Windows Explorer. The Read-only and System attributes is only used by Windows Explorer to determine whether the folder is a special folder, such as a system folder that has its view customized by Windows
Leads me to believe, there was or is malware on your system.
i have no clue as to why this happened.
The work around I found was to down load this defrag program.
You may ask, so what's the difference, The attribute READ ONLY, has been set on the windows defrag program, I suspect on a file used when the analyze portion is being run. Thus you would get the read only error message. The new program will use a different file name than the windows version and should run just fine. The challenge for me at this moment, is finding which files attribute has been changed.
At this point you have a couple of options 1. Run the defrag program. (The one that you download)
2. Open a post in the Malware section, have them give you a clean bill of health.
I would like to do step 1, just to verify the workaround actually works.
Then I would most definitely go to the malware forum.
I will ask around and continue to research for the answer while they are checking your system.
