Ah! Well, now we know what it is
It's a nasty one: it's the "December
13th" virus: on December 13th it will attempt to erase your hard disk.

Fortunately, it's also very old, so your anti-virus program managed to
identify it, and will have no trouble removing it from all of the files it
finds it in.
If it cannot successfully remove the virus, it will quarantine the host
file. I would normally delete anything an AV program puts in quarantine: if
it can't fix it, neither can I.
Yes, it is a war of attrition. You should be OK now for a year or two,
provided that you update your antivirus definitions at least once a month
and stay clear of websites that attract teenagers
One of the most effective defences is to run as a Limited User. On both PC
and the Mac, I login as Administrator ONLY when I need to install software
or perform system maintenance. Both at work and at home I run as a limited
user all the rest of the time. That way, the bad guys can never GET full
control of the computer, which absolutely prevents them installing their
crud in such a way that you can't find it or remove it. If I did get
something bad come in, I could just trash the User ID and the rest of the
system would be OK.
Protection against "malware" is getting better all the time. Unfortunately,
so is the malware... I guess the bad news is that the better and more
popular Macs get, the more malware there will be out there that will hammer
a Mac.
Sadly, the game has increased in ferocity. I can remember the first Word
viruses wee known as "Prank" viruses, were confined to doing irritating
things to Word, and were created by sad schoolkids.
Now some of the best and most highly-qualified programmers in the world are
creating them for organised criminal organizations and nation states (e.g.
The CIA...).
This stuff is no longer "funny". It's capable of great damage, and the
worst of them leave no sign they've been there.
All we can do is run the latest protection software, keep it updated, and
make sure our backups store data for more than a year (it can take a year
before you realise that last year's tax return or whatever has been
interfered with). So we need to make sure our backup runs daily and that we
can easily get back a year if that's what it takes to find a clean copy of
your data.
Cheers
