Hi there. You have nothing too serious on your log, and the Myzor.FK infection you mention is certianly not present. You might like to do the following though...
Reboot into safe mode, and tell explorer to show hidden files and extensions. (no need to turn off system restore for this, as your log isn't too bad. Unless of course you didn't turn off system restore when you were following the instructions, in which case do so first, and re-enable it once you've finished)...
Open task manager, and end the task
symlcsvc.exe
Go to add/remove programs and...
uninstall DAP (Download accelerator plus)
uninstall anything to do with symantec (not spyware, but I see you've changed antivirus!

thumbs up

and you have a residual service)
Spyware detector (it's complete rubbish)
run HJT and let it fix the following entries...
