It seems the problem has finally got wider exposure on the web, as
more and more people were being hit by it. A piece of information
that I found most helpful is this post on the Apple discussion forums
As it turns out, Hacktool.Underhand isn't a virus or Trojan, but
simply a bug in Norton AV's latest virus definition file, which was
too broad and identified legitimate background system maintenance
tasks, such as management of swap files, as viral. Symantec has
finally acknowledged the problem and released yesterday (May 5) a
corrected virus definition <http://securityresponse.symantec.com/

At present I'm not using anything: I simply take care to never open
(or forward to other people) an email attachment before checking from
other sources that it is legitimate; and (but that's more antiscam
than antivirus) to always look at the source of email messages
containing hyperlinks, before clicking on them, to infer from the
html code whether the hyperlinks actually do what they pretend to be
But that's just stopgap measures: I would prefer to have an antivirus
running, and I'm waiting for an update to be released, compatible
with Tiger. Though, as a Virex user, I must confess that, after a
brief trial period, I had disabled background scanning and scanning
of mounted volumes, to only leave scan-on-demand, for performance
issues (and because I don't like very much to have background-running
software, other than the OS, to avoid unhappy interference).
Or maybe Apple did suppress Virex from .Mac on purpose, and is
working on a home-brand antivirus software, to be announced at
Steve's WWDC keynote?
