IMO...you have waited a long time to seek assistance...and, based on the number of systems you mention and the process of dealing with each one...I would say that you have a serious problem.
If you truly reformatted, deleting previously infected partitions...that should have solved it for a single computer. Having a clean computer networked to an infected one...well, that just starts the whole problem all over again on that system.
I suggest that you follow the prescribed procedures at Preparation Guide, Before Using Malware Removal Tools and Requesting Help - http://www.bleepingcomputer.com/forums/topic34773.html
and then submit the requested logs in the proper manner at the forum referenced in the Prep Guide. The folks there will guide you in what approach should then be taken.
