SpywareBlaster 3.4 Under the Restricted Sites tab, I clicked the option (to check it) for "Restrict the actions ..." which adds a list of sites to the Restricted Sites list in the registry key. However, when this option is disabled, not all of those bad sites are removed from the registry keys. I also went through all the thousands of entries to uncheck them (because of the sucky GUI that doesn't let users select all using Ctrl+A or select some using Ctrl+mouseclick or Shift+mouseclick) and clicked the button "Remove protection ..." but still many bad sites were not removed from the registry. I would monitor the following registry key: HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings\ZoneMap\Domains Under gets added a registry subkey for each domain regardless of which security zone under which it is used. A data item under the domain's registry subkey specifies in which security zone it belongs. Okay, so why is SpywareBlaster adding domains that have no data item to define in which security zone it belongs? That is why disabling or removing the domains using SpywareBlaster doesn't remove them all because some don't belong to any security zone. I looked at the ones that SpywareBlaster would not remove. These are also not listed in any security zone when using Internet Options -> Security -> Restricted Sites -> Sites (or they refuse to be deleted using that method). What I saw was, for example: HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings\ZoneMap\Domains\008i.com for the 008i.com domain. In that subkey was defined a default data item (with "*" as the data item's name), as follows: data item name = * data item value = 4 The value of 4 means that domain is listed in the Restricted Sites security zone. So then I disabled the Restricted Sites list in SpywareBlaster which removed most but not all domain subkeys and looked at one of those that got left behind. I'd see: HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings\ZoneMap\Domains\cjb.net but it has NO data items defined within that subkey (and, no, the "(Default)" that is shown means no data items are defined in that subkey). So SpywareBlaster will add absolutely useless entries in the registry for domains that end up not being assigned to any security zone. In other words, SpywareBlaster adds "bad" domains which are totally unusable within IE's Restricted Sites security zone - so those sites are *not* restricted! Below is a list of the dataless domains added by SpywareBlaster: 1gb.ru american-teens.net cjb.net com.au com.br com.ru data-line.us dulcineasystems.net exaccess.ru gratisdownloads.nl host.sk jps.ru narod.ru netfartpost.com ntcor.com picture-posters.com pornpic.org rack.cc scourweb.net spb.ru tucows.com webhost.ru Until this gets fixed, I've had to disable the Restricted Sites list in SpywareBlaster and follow by cleaning up the registry. Before releasing a list of bad sites, perhaps they should actually be marked as bad so they get included in the Restricted Sites security zone - and that means some quality control before releasing the list by scanning each entry in your list to check that a data item is defined that specifies the Restricted Sites security zone. Also, when the user disables SpywareBlaster's Restricted Sites option, that doesn't mean all entries will be removed. Could be SpywareBlaster's list has changed since last used so a site listed before is no longer in the list, but disabling the option in SpywareBlaster will not clear out these old remnant registry keys. Either an option should be provided to clear out the list in the registry (and not just for the domains in SpywareBlaster's list) or the user reminded to use Internet Options -> Security -> Restricted Sites -> Sites to check for any remnant sites that should be removed/added.
