rkill would not be a problem, goored fix and TDSS maybe. I also see you have posted this identical problem at Bleepingcomputer on June 27th. You should never post the same problem at two different forums. You should stick with just the one.

Honestly I don't know where to tell you to begin. You have used a rogue program multiple times which probably has damaged system files. You remember using 3 other high powered tools meant for another computer's problem sometime in the last few months. I don't know what other programs you may have run. Your best bet may very well be to reformat and reinstall and start fresh since there is no way of knowing what damage even the legitimate programs may have done.

MBA-M would not have damaged anything, neither would ESET but since I don't know what else you may have run I just don't know for sure where to tell you to start. There may be too much system damage to try to fix.
