Summary:                    Some files are wrongly reported as having a bad
Heads up:
There is a bug in 0.97.5 which makes it report some files as having format

This happens on some Solaris related files, eg:
/var/tmp/137081-07.zip: OK
/var/tmp/137148-07.zip: OK
/var/tmp/137321-02.zip: Can't unpack some data ERROR
/var/tmp/138823-10.zip: OK
/var/tmp/138827-10.zip: OK

----------- SCAN SUMMARY -----------
Known viruses: 1278842
Engine version: 0.97.5
Scanned directories: 0
Scanned files: 4
Infected files: 0
Total errors: 1
Data scanned: 80.28 MB
Data read: 22.60 MB (ratio 3.55:1)
Time: 18.295 sec (0 m 18 s)

It also happens to me on some Red Hat RPM files, and a handful of others,
.gz, .bz2. This bug is cross-platform, I first noticed it on RHEL5 with
rpmforge ClamAV.
Of course those files are perfectly fine:
No errors detected in compressed data of /var/tmp/137321-02.zip.

An upstream bug is already open, there's apparently no official fix at this
