well, i put most of my problem in the title...

i did a virus check on my 'puter with ClamWin (opensource) and it said that winamp's in_mpc.dll had some kind of trojan in it.

my computer's been stable, and i'm not worried, but i'm curious as to whether this is a false-positive from the virus checker, or maybe there's really something up with in_mpc.

i have 2 installs of winamp (2.8 and 5) with this plugin, and they both were found by the scanner.

in_mpc.dll: Trojan.Flood.22016 FOUND

is anyone aware of this issue? or should i re-download this plugin and scan again?

From where did you dowload that file ? Could you please post md5 hashes for the suspicious files ?
Try some other antivirus software as well. TrendMicro Housecall is a free online scanner for example.
Probably and hopefully it's a false positive.
The one I use:

Winamp musepack plugin 0.96 (date 2002_07_07 124416 bytes):
1D2176124607BB2BDED6BCE1A322619C in_mpc.dll

they're both:

98DEF7244192932D1BA56D40D593505E

hmm. that's different to yours. i'll try download again from rarewares.

i used "DAMN Hash Calculator" to generate that line. not sure if this is much good or not...

[edit]

the rarewares download for in_mpc_0.99d_alpha has the same checksum. i guess it's a false positive.

Clam AV got a pretty devastating result in a recent c't review. Their reaction time for new viruses is way too slow, therefore it has a bad detection rate with most newer viruses (and the new ones are always the most common ones around). Ok, it's Opensource and still in early stages, so that's excusable, but i wouldn't use it as a serious AV program yet. Maybe you should make a Bugreport about a false positive.

good thinking... i was wondering whether to report that.

i know it's a pretty limited program... but i'm getting behind opensource (and my norton license expired, and i was too lazy to renew it)

Try your file with these two AV packages, they are both free (as in free beer) and pretty updated:

AVG FREE Edition
Antivir Personal edition

Another good freeware virus scanner is eScan Antivirus Toolkit Utility which is powered by Kaspersky Antivirus, it's free and is updated each week.

It that HASH calculator complies with the RFC, it will produce identical results to any other MD5 hasher. If you aren't sure, try these:
Fourmilab MD5 Which is very quick
Windows GNU utils Which is a port of the GNU version

You could mail that file to me, or put it on some web space (uploading here probably isn't wise) and I could scan it for you with the latest Norton and McAfee.

I also recommend AntiVir Personal Edition - definition files are updated daily(!)

i'm not too worried about current virus checkers - i'm firewalled, and i don't open spam, so i feel i'm protected as well as i can be.

i've submitted a report to the clamwin guys. we'll see what happens
