Ich persönlich kann das natürlich nicht beurteilen. Ich gebe einfach mal verbatim die Konversation von heute Morgen wieder:

[25.02.2011 10:01] <Wolfsherz> Hi, openttd.exe seems to contain a virus (TR/Dropper.Gen). Version 1.1.0-RC1. Reported by Avira AntiVir Professional.
[25.02.2011 10:04] <Terkhen> Wolfsherz: from where did you download your openttd?
[25.02.2011 10:05] <Wolfsherz> i always and only download them from openttd.org
[25.02.2011 10:07] <Wolfsherz> it is reproducable also. i deleted the file, redownloaded it from openttd.org and AntiVir detects the virus on unpacking the archive.
[25.02.2011 10:08] <Terkhen> unless we (or one of the mirrors) were somehow hacked that detection does not make much sense
[25.02.2011 10:09] <Terkhen> given the description I found of TR/Dropper.Gen, it might be detecting that OpenTTD downloads compressed files and then unzips and runs them somehow
[25.02.2011 10:09] <Terkhen> but this is not something I know much about
[25.02.2011 10:10] <Wolfsherz> notice that i did not run the file, it was detected on unpacking the downloaded archive
[25.02.2011 10:10] <Yexo> Wolfsherz: do you know from which mirror you downloaded openttd? also the 32bit or 64 bit version?
[25.02.2011 10:11] <Wolfsherz> http://binaries.openttd.org/releases/1.1...-win32.zip
[25.02.2011 10:11] <Yexo> if you go to http://binaries.openttd.org/releases/1.1.0-RC1/ , on which url do you end up?
[25.02.2011 10:14] <Wolfsherz> http://de.binaries.openttd.org/binaries/...index.html
[25.02.2011 10:31] <Terkhen> avast does not complain about that file
[25.02.2011 10:32] <Wolfsherz> well, that is great... but avira does
[25.02.2011 10:33] <Wolf01> even avg doesn't complain
[25.02.2011 10:35] <Wolf01> "it might be detecting that OpenTTD downloads compressed files", yes, OTTD does it for online content, Avira is too zealous
[25.02.2011 10:36] <Wolfsherz> i suppose developers will contact avira and tell them it is a false positive then?
[25.02.2011 10:39] <Wolf01> http://forum.avira.com/wbb/index.php?pag...adID=77575 you can do it as well
