what does this file mean? C\:\\nppdf32Log\\debuglog.txt

  It was only last week that I realised I had that file in my home 
directory. I do have Acrobat Reader installed, but I have had it for 
ages, so why is it that only recently the file 
"C\:\\nppdf32Log\\debuglog.txt" appeared on my home directory? Something 
changed, most likely in Acrobat Reader, though it could also be in 
Firefox or Seamonkey. Last week when I found the file I deleted it, and 
today it was there again. I deleted it again, googled for a PDF within 
FF, opened it

I have found that a good way to delete such files is from the terminal 
rather than the GUI.
First rename the file from say .txt to .txx then delete the altered file.
