cookie dat

If you want to just remove the file, try creating a batch file to remove it upon start up. If you need help with creating a simple batch file to do that, let me know.
If you want to clear out cookies, you can just manually delete them using IE settings, Netscape settings, and going in the folder to delete manaully. Even change the patch of both temp internet folders (where they place their chache) and move them into the actual TEMP folder in Windows. That way, you can delete everything, along with other junk, at once. That is how I do it.
I use Norton Cleansweep (to clean what is left after after doing the previous three suggestions) and Internet Security (to block). If you want some free software to look at, I would check out CookieCop 2(?) at http://www.pcworld.com. They have a bunch of other useful cookie tools.
Let me know how else I can help.
