One More Hacktool.Rootkit and Trojan.Zeroaccess/Gen.2 Infection to Add to the Pile

There seem to be a ton of these recently.  This popped up randomly after connecting my laptop to my family's wifi network, but none of them seem to have any such problems.  I'm half suspecting it's due to having Vista (64 bit) while they all have Windows 7.

 

Norton Internet Security is popping up constant messages that it is blocking attacks, involving three separate things: the 80000000.@ Hacktool.Rootkit, the desktop.ini Trojan.Zeroaccess, and the desktop.ini Trojan.Gen.2.

 

I've run all the Norton tools I can over this, and nothing has worked so far to fix anything.

 

I've been making a complete backup of everything on the computer, but I've definitely been getting an excess of desktop.ini files in my backup folders.  I've only been copying things out of the Users folder and a few key program folders (no Windows directories), but I'm worried the backup might be infected with this too now.

 

Any help anyone can offer would be appreciated.  If my backups can be proven safe, I'm not worried if I have to reformat, since I was planning an upgrade to Windows 7 anyway.

 

Running NIS 19.7.1.5, on Vista 64.  Thanks!
