Guys, help me out here. There are these three files on my hard drive - AcrolEHelper.dll, AcroPDF.dll and pdfshell.dll that refuse to delete. When I try to delete them, I get an error message - "Access is denied. Make sure the disk is not full or right protected."

When I format the partition, the files remain intact. I have tried file shredders but they fail to delete the files. They exist in this location and even in the partition where I have windows installed C and D: \Program Files\ Common Files\Adobe\Acrobat\ActiveX.

If you know a way to delete these files, please let me know. I currently have Windows in the D partition.
