How do I delete a cookie that keeps changing its filename?

I don't understand how it is doing this. I just got the free version of Spyware Doctor today and I was cleaning up a lot of the spyware it found on my computer. In my cookies folder there is one cookie named 'default@go[2]' that keeps changing its name every ten seconds or so to 'default@go[1]'. I can sit here and watch it change intermittently. Windows won't let me delete the file because it doesn't recognize the filepath (I assume because the file changed names after i clicked delete). I've tried renaming the file myself, and then deleting it. I can delete the file when I do that, but in ten seconds it reappears. This is freaking me out.
