An analysis of your HJT log shows the following problems :
O2 - BHO: (no name) - {5C255C8A-E604-49b4-9D64-90988571CECB} - (no file)
As an 02 entry, this is bad. It should be an 09 entry. This one should be removed.
O20 - Winlogon Notify: spba - C:\Program Files\Common Files\SPBA\homefus2.dll
If you recognize the program Protector Suite QL from UPEK Inc, this one could be OK.
If you do not recognize this program, I would remove it. It appears to be a legitimate program.
