infected explorer.exe etc.

Ok so i may be a little vague, been trying to sort this out for far too long.
came home to find my computer with no explorer running and set about trying to sort it out.
im sorry if it makes it difficult, i didnt follow your guide from the start because i only found this site an hour ago. but ill tell you what i have done.
using programs including spybot / spyware doctor (full edition) / malwarebytes and a couple vundofix programs i found quite a few infections of virtumonde, along with other things like win32.delf.uc (which i dont seem to be able to get rid of)
so i cleaned them off, this didnt really seem to help things, i now can use my pc in safe mode and explorer doesnt close. This is when i found your site, and since then ive followed all your cleaning etc. steps.
i cant install SUPER anti spyware, something about the administrator has disabled installations of that type, but everything else is done.
i have been considering just reinstalling winXP, however im not sure how it would work, because i have XP installed on one of my hard drives and Vista on the other, would they both need to be reinstalled??
also i have a lot of data and not so much space to backup to, unless i want to sit here with DVD's all day.

i shall include a couple more logs from last night to help you recognize my problems.

any help you can give is greatly appreciated, and as i said im very tired so i may edit this to keep it up to date

other files

again sorry this is messy.
an updated MBAM log is here also, along with a DDS log i did from another program, not sure if it will be helpful, the info might be out of date but will show what ive had atleast.

also, when i run MGtools i get this pop up message 'The application failed to initialize properly (0xc000007b). Click on OK to terminate the application'

thanks again

 

also managed to get the SUPER anti spyware working, here is its log

 

nice...
just what id always wanted

 

actually if you could tell me one more thing, like i said i have win xp installed on one hard drive and vista on the other - do i have to completely format everything?? or just my xp installation?
