I don't guarantee that I've found everything (or indeed anything) in a very long HJT file. But the below extract is potentially dodgy IMO:
---------------------------------------------------------
R0 - HKCU\Software\Microsoft\Internet Explorer\Main,Start Page =
R0 - HKLM\Software\Microsoft\Internet Explorer\Main,Start Page =
O2 - BHO: (no name) - {02478D38-C3F9-4efb-9B51-7695ECA05670} - (no file)

O2 - BHO: (no name) - {549B5CA7-4A86-11D7-A4DF-000874180BB3} - (no file)

O2 - BHO: (no name) - {BBE59AF5-EE22-4A3A-AB26-3F774D1B4216} - e:\PROGRA~1\FOLDER~1\FOLDER~1.DLL
O2 - BHO: (no name) - {FDD3B846-8D59-4ffb-8758-209B6AD74ACC} - (no file)

---------------------------------------------------------

I wouldn't have expected in a normal system the IE start page to be null, but you may well have blanked it for security reasons.

The other entries need invetigating and the process involving HJT/ComboFix and other tools as per many posts in this forum would seem in order.
