When I had problems with things sending out information over the internet, SBS&D found them and put them at the top of the list with checkmarks in the boxes.

The Adobe stuff and similar found items are just lists of files that were recently loaded into Acrobat and the like. They're history lists generally. If you're worried about people looking to see what you've been doing on your PC, they're good to remove. But I'm not so I haven't. :-) None of the information is sent back to Adobe (AFAIK).

More information about the files found can be examined by highlighting them (click) then click the "Description of this product" button at the bottom (or alternatively right clicking on it and selecting the same).

HTH.

Cheers,
Scott.
