Probably because I can find no information on an infection called Clicksor. Clicksor is a marketing technology but I see no evidence of that on your log either. Can you explain more fully? Are you CERTAIN this is the name of the infections and if it isn't detected then how do you know you have it?

I honestly don't see anything related to Clicksor in your log.
Did either of your scans find anything? They wouldn't say Clicksor, they would say something else.
Update MBA-M and do a Full Scan with it.
Remove everything found
Save the log.
Reboot

Post back with the log.

Hi guys! Could you help me please? My PC is infected with Clicksor and both Spybot S&D & Malwarebytes' AM have failed to detect it. Here is the HJT logfile below:
