To be honest I usually run (or tell someone to) the antivirus on an
infected machine through a remote connection such as ssh2, or as Windows
network administrator. That takes care of several issues. Antiviruses
are great warning systems, but limited, they run locally for instance.

However, if executables are changed or I have a suspicion that the
machine is rooted, based on the type of infection or behaviour... I
backup and scrub the computer then reinstall from scratch, preferably
with an image.

Playing with viruses and rootkits is fun, but it's playing, not getting
the mail delivered or clients served.

At the moment, I suspect that the malware still there because the AV may not capable to clean them all. I tried using 3 or 4 most popular AV, but all were claimed the servers are clean while my software couldn't run smoothly. In fact, some of exe files has been changed in size while I am not sure whether this changed made by viruses or 'bad' AV I just installed.
