Yups.. I remember that incident.  Very similar..

Every .html file and every index.php file (where it was smart enough
to include a ?> before the malicious code.

Yup, I'm not a big javascript user..  There is probably some
not-of-my-making on viewdata.org.uk as it's using a simple CMS
software, but on the whole I prefer coding stuff server-side.  I've
more control of what things end up doing!

It seems not.  It was set to auto-update every day too.  AVG free ...
I'm now on Avast, which seems better at blocking web based stuff.
Still had a lingering infection, though, and ended up running
something called "combofix" which found it.  Got taht from here:

Indeed...!

On the plus side, it seems the hosting co were working through the
night clearing it up, and running scripts to clean all the affected
pages off again.  I'm still going to fetch everything back local and
grep for iframes, though I think.

Sometimes I hate not being in control, but I've run my own hosting,
and it became a pain in the neck, just keeping on top of the security
and version updates all the time.

Cheers!
