Hi,

I happen to have a similar issue and thought I could append to this
thread with my questions.

>> Is there a way to delete a signature that you are not interested in?

I'd like to create a local whitelist for patterns that create false
positives in my environment from attachments in email. Here's an
example:

Dec  1 10:47:55 mail01 amavis[18312]: (18312-02) Blocked INFECTED
(PUA.Script.PDF.EmbeddedJavaScript), [204.XXX.YYY.21]
[204.XXX.YYY.21] <[email protected]>, quarantine:
virus-06232854a5c3b09c7451be840f81fc58-20111201T104753-18312-02.gz,
Message-ID: <01b601ccb040$933b3bf0$b9b1b3d0$@[email protected]>,
mail_id: 539J2GR60fLp, Hits: -, size: 1288479, 1411 ms

Dec  1 10:47:55 mail01 postfix/smtp[18345]: 081AC160468:
to=<[email protected]>, orig_to=<[email protected]>
, relay=127.0.0.1[127.0.0.1]:10024, delay=7.3, delays=5.9/0/0.01/1.4,
dsn=2.7.0, status=sent (250 2.7.0 Ok, discarded,
id=18312-02 - INFECTED: PUA.Script.PDF.EmbeddedJavaScript)

I understand I can add PUA.Script.PDF.EmbeddedJavaScript to
sigwhitelist.ign2 for it to be whitelisted, correct?

However, this will be overwritten, so I'd like to create one of my
own. Do I just create a new file in that directory, and signal clamd
to re-read the database?

Is it possible to whitelist based on the name of a file?

This also seems like a very generic signature. To determine the
pattern that matched within the attachment, is this the correct way to
do that?

# sigtool -fPUA.Script.PDF.EmbeddedJavaScript
[daily.ndu] 
PUA.Script.PDF.EmbeddedJavaScript:0:0:255044462d*6f626a{-2}3c3c{-100}2f4a617661536372697074(20|28|3c)

Thanks,
Alex
