HELPROOM ASNWER The Mats Run program is a Microsoft automated troubleshooting tool. It shows what it thinks are add-ons to Internet Explorer, but some are idle components of other installed software. Examples include BitDefender and PDF Creator.
Many add-ons in the list you attached to your query are browser toolbars, not add-ons. These can be easily disabled: right-click Internet Explorer's toolbar and deselect any you don't use. In some cases, you'll need to look in Manage add-ons or Add/Remove Programs to disable them.
Finally, run a full antivirus and spyware scan to ensure that none of the entries detected by Microsoft is malicious.
