The entry I refer to is the one below. Your log does not show SpywareBlaster running. I assure you, this program, spywarebot IS on the computer and set to run at the Startup of the computer.

It shows in both the CWSShredder scan here;
RUN: [spywarebot] C:\Program Files\spywarebot\SpywareBot.exe -boot

and in your HiJackThis scan here;
O4 - HKLM\..\Run: [spywarebot] C:\Program Files\spywarebot\SpywareBot.exe -boot

I find NO indication, in either log of the program SpywareBlaster(which IS an excellent program).
