First, I find it odd that you're asking about how much the CEH exam costs, in another thread, while asking about this. It seems that MAYBE you've been poking around to learn some security (for whatever intention) and gotten yourself infected by trying to use some possibly 'less than ethical' material you've pulled down.
That said, IF you're legit... (I'm sorry, but this really does sound fishy to me... how about any other EH-net-ers reading this???)
All of the various things you've mentioned are helpful in eliminating spyware, viruses, rootkits (in the case of total drive wiping), etc. If this truly keeps coming back, I'd only have a couple of good suggestions.
To begin with, if this is as serious as you lead us to believe, disconnect from the internet, before doing anything else. Disconnect your entire home network.
1.) Wipe ALL machines, at the same time, all together, to ensure something isn't returning from one machine to another after cleaning up.
2.) Throw away ALL data you have stored, or at a minimum, have it professionally analyzed, to be sure that you don't have a remnant on USB key, external drives, or other storage media (ie - cdrom / dvd om backups) This includes ANY installation media, with exception of store purchased CD / DVD install media for retail software, such as MS Windows, etc. (Although, you COULD check them out to be safe, since you seem to be getting infected again so quickly, to ensure somehow, you didn't get some crazy, virus-laden media that somehow got onto shelves.)
3.) Email... print any you've wanted to keep saved (including those from online mail, such as GMAIL), then wipe all mail from your mailboxes, both on your local machine and the online mailboxes, to make sure something isn't slipping back in.
4.) remove yourself from ALL social media sites for a while (stop logging into facebook, myspace, etc, in the event you're somehow hitting someone's infected graphics posted therein, on a profile, etc.)
5.) Lastly, if you use a static IP, or if you host your own website and use DYNDNS or something to route to your local box with a hostname, change the hostname you use, or ask the ISP to change your static IP. If EVERYTHING has been wiped, simultaneously, and you've done everything else, I find it hard to believe that someone randomly keeps finding you.
If none of this helps, and you keep getting hit again, then my advice would be to look at your close friends. If your 'home' network has that much equipment, and you're looking to do security, etc, then I'd be willing to bet you've also had other folks you know, near your machines.
That said, though, I think, based on your two separate posts, that I'm not totally certain you're being totally honest here, so think hard before asking the next questions.............
