Hi. I'm aware that there was a thread on this subject about 18 months ago but I don't remember seeing a really definitive answer to this particular question. Every time I run a Spybot scan it records 2 entries for CoolWWWSearch.SmartSearch and 4 entries for MySoft. I would like to put these into Spyware Blaster's Custom Blocking but need the appropriate CLSIDs. The perennial question is, how can I find these elusive references,please.? There must be a CLSID "factory" somewhere.!! Cheers, Haba.
