It seems to me I get a whole bunch of false positives for Heur.Corrupt.PE
for all bzip compressed tar files, *.tar.bz2, as well as for *.exe.dbg files
in cygwin.
Would be better if Comodo identified (unpacked?)
all these files.
I could contribute some of these files if you are interested,
to check I am not wrong about false detection.
Check at virustotal reveals only 4 hits for this virus,
but what they all look for is probably the compression
method…
