Did any of those scans yield any results?? MBAM will detect it. Did it do in your case?? Why can't you connect to the net?? What is the error/problem you are facing?? All sites or just few sites?? tried any other browser??
Open the Registry Editor, go to Start > Run > type regedit and then press the "OK" button.
Del the following Registry Key :
HKEY_CURRENT_USER\Software\Spyware Protect 2009
Also manually search for the "Spyware Protect 2009" folder and delete all its contents...
Is your MBAM upto-date?? To be on the safer side Update it, 'Perform a Quick Scan', remove all infections, save the logfile and reboot. Provide the logfile here..
As For HJT, log looks ok to me as far as infections are concerned.
just answer the questions in 'red' maybe the issue is not malware related or maybe some malware has done some changes which have to be reverted...
