Re: [OctDev] my virusscanner found a Worm in octave.exe

[Michael Goffioul]

I'm a little bit puzzled by these results. I scanned octave.exe through
http://virscan.org and only 2 (out of 36) AV detected the Zhelatin worm:
Antivir and Ikarus. From user reports, the previous 3.0.0 version also
has the same problem, but this release dates back from December 2007
and has been downloaded more than 70,000 times. Is it imaginable that
a worm was present at that time and that nobody detected it during
6 months...? All this makes me think there's a higher probability that
this is a false positive detection.

Michael.
