From what I see in your list there is nothing unusual. The fact that 5 items caused the problem that you mentioned is unusual and may have been caused by the browser that you installed.All the problematic items can be unchecked as they are not essential.
In principle you need only antimalware programs to be checked, and I don't see any installed. It is very important that you have an Antivirus installed.
The checked items are programs that open and run in the background, drawing computer resources even when not in use. Yahoo messanger, for example. If you want it to be loaded as soon as you start your computer then leave it checked. Alternatively, you can leave it unchecked and have your computer running faster, clicking Yahoo Messanger's icon on your desktop, or task bar, when you want it open. Another example is Adobe Reader. If you want a PDF file to open as soon as click it, then leave Adobe checked. If you want your computer to run faster, uncheck it and click the Adobe icon when you want to open a file.
You can always change your mind and recheck unchecked items.
