I have 2 concerns that I would like some help with:

1. I have discovered several hundred items in my registry (in the Domains key) that I did not put there.  Apparently these are called "sub domains".   My  antivirus program cannot detect these.   I would like to know if there is a setting for RegVac  to detect and remove these automatically.  (I also have A1 Click Ultra PC Cleaner)

The path for these items is:

HKEY_Current_User/Software/Microsoft/Windows/Current Version/Internet Settings/Zone Map/Domains

2. Using the same path with a slight alteration there is a "History " key with hundreds of subkeys in it.  It looks like a lot of advertising:

HKEY_Current_User/Software/Microsoft/Windows/Current Version/Internet Settings/P3P/History

All of these sub keys Under History and Domains) seem to be added after visiting certain sites but I don't know which ones do this.  I'm not the only one using this computer.  I can delete these keys manually with no problem and they don't show up for weeks and then they are there again.

   The Domains key is for listing restricted domains.
   The History key is used to enable or disable cookies.
   See this website for more information on these - http://support.microsoft.com/kb/182569
   I do not think that it would be wise for me to add these to RegVac to be cleaned since they do have a valid use.
   If you want to have RegVac clean them, you can set it up to do so using the Add button in the Stash Cleaner of RegVac.
