Re: [HTCondor-users] Fwd: URGENT - HTcondor condor_8.4.9-382747-ubuntu14_amd64.deb INFECTED - Benjamin.

I got drweb working on the 32-bit EL6 BaTLab platform, and it
does indeed seem to think that
condor_8.4.9-382747-ubuntu14_amd64.deb is a threat, specifically
the usr/lib/condor/libexec/condor_ckpt_probe file inside.  I
tried to extract the file uzing xzcat and tar, but for some
reason have been unable to so far, even though strace claims
it's being written to disk.
