Well, until you get rid of it all you can't really be sure
that is the only problem. LIkely it is but until then...

Yes, that's their desire. Desire not always equal to
necessity. You do what you can, and when it looks like it's
going to take a dozen hours to do what you were charging $10
for or for free, you either renegotiate, learn from this not
to jump to an estimate beforehand, or inform them that it's
necessary to reinstall. Reinstall does not mean losing
"all" their stuff though, there's no reason any data that is
intact can't be salvaged. I'll make a few suggestions
below.

Boot system to safe mode, never have it hooked up to a
network (nor internet) when networking is working
(non-safe-mode, but really, never).
Uncheck all items in MSCONFIG that load at boot time. Get a
CDR or thumbdrive or whatever to get tools onto the system.
Google for some of the software if you dont' have it yet.
"Hijack This" should be ran. It'll find a lot of stuff...
you may need to contact the owner to find out what printer
and scanner they use, as there's no need to
remove/disable/etc their needed software, only that left
over from the past or unwanted stuff. Hijack This needs run
on the system, as will portions of programs that scan the
registry or windows OS related files, but sometimes it can
help to pull the drive and put in another system, NOT
booting to it ever, just to scan it as a secondary drive.
If some programs do multiple types of scans, for example
Adaware scans registry and files, you may need to run it on
their system, but after you'd put the drive in another
system and ran adaware (and likewise, antivirus and other
scanners) to remove the files first. Key to getting rid of
stuff is to keep that stuff from loading, as some are rather
sophisticated and will even repair themselves.
Identification of the infectious agents is useful, if you
suspect there's more to be rid of sometimes a scanner can
find part but not all as it's a different strain of malware.
Multiple antivirus scanners should be used, with current
updates of course. Sometimes there are specific tools to
remove things, or classes of things (like CWShredder).
As silly as it might seem, i also suggest checking
add/remove programs. Some stuff is plainly listed there as
the malware company wants to pretend they're legitimate, or
might rightly be if the system owner installed software that
required (through the license/EULA) adware or similar to be
installed in parallel. This may also mean that some
software the user "thought" they wanted, needs reconsidered.
When all else fails, if you simply can't get system running
properly and find it necessary to reinstall everything, you
can easily enough dump off the files onto a CDR or a few,
all the data and favorites, shortcuts, stuff on desktop,
whatever... there is no need to lose any data, at most they
might need reinstall applications and set user preferences
(tweak the OS).
If it becomes necessary to do more antivirus scans, isolate
the system from the rest of the lan if you allow IT to
connect to internet, but first do as suggested above, scan
the drive while in another system so none of the code is
running. There are several online antivirus scanners, the
following is not meant as a comprehensive list,
