RE: [Declude.Virus] How to check VIRUSCODEs

[Colbeck, Andrew]

Title: Message

The return code = 8 in F-Prot does mean "suspicious file" and not "virus".  In this case, they are not calling the executable Bagle, they are calling it Mitglieder, which is a Bagle-related file and is commonly seen as a dropper.   I sent a support request asking them reconsider how they are classifying this executable.  I'm not holding my breath though, because previous email support response time as been between 4 days and 2 weeks, by which time I expect this particular problem to be gone.   In fact, I'm seeing no new warnings in 15 hours.   Also, I spot-checked a few IP addresses that had sent us multiple copies, and one came from a known spammer block (as listed in SBL) in Brazil, and another from Korea.  I used to think it was the spammers who were sloppy and had infected machines; nope, it's pretty clear now that the spammers and virus authors are collaborating.   Wouldn't it be nifty if Declude shared some stats on their MTLDB database vis-a-vis correlating IPs that send viruses to IPs that send spam?   Andrew 8) -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Matt Sent: Wednesday, April 20, 2005 8:35 PM To: Declude.Virus@declude.com Subject: Re: [Declude.Virus] How to check VIRUSCODEs What you have means that a matching virus code was found for each scanner.  If a scanner throws a code besides one that you specify, it will be logged in much the same way that the virus is shown.  The following is exactly what F-Prot will show when it throws a code of 8 and when you aren't configured to tag that as a virus:     04/20/2005 00:28:37 Qda6b06e0014e9ee2 Error 8 in virus scanner 1. We're going on 5 or 6 days now where F-Prot has been throwing a Virus Code 8 for some newer Bagle variants, and it is starting to look more and more like this is purposeful, though if so it would also be short-sighted.  Maybe someone should contact F-Prot and ask for an explanation and indicate that it would be helpful not to mix the codes like this for known viruses.  Apparently Virus Code 8 can hit non-viruses, and I think it will throw that code when it detects an encrypted zip of any sort, but I'm not certain about that either.  I would certainly prefer to not have to rely on Virus Code 8 in F-Prot because I don't want to be deleting E-mail that doesn't contain a virus and where Declude offers better granularity (such as only banning encrypted zips with a banned extension within it). Has anyone contacted F-Prot?

Adding viruscode 8 will at least stop them. How do you see if there are any code 8s in the virus log file. I use F-Prot and McAfee. My viruscodes for F-Prot are 3 and 6 and for McAfee is only 13 An example of a virus 04/20/2005 05:03:10 Q1AB803D9008C6B32 MIME file: demo.exe [base64; Length=40800 Checksum=4318001] 04/20/2005 05:03:10 Q1AB803D9008C6B32 Banning file with exe extension [application/x-msdownload]. 04/20/2005 05:03:10 Q1AB803D9008C6B32 Scanner 1: Virus= W32/Plexus.G Attachment=demo.exe [2] O 04/20/2005 05:03:10 Q1AB803D9008C6B32 Scanner 2: Virus= the MultiDropper-KR trojan !!!

If you want to buy full base, please reply me...   The only thing that I see that resembles my viruscodes is the line “File(s) are INFECTED [ W32/Plexus.G: 13]” and the 13 in this line is from McAfee (scanner2). I do not see any result from F-Prot (scanner1). I am logging on high.
