With regard to the Antispyware module not showing up - this is normal for 8.8: antispyware is rolled into VSE and doesn't report as a separate module.
The column sorting thing is a known issue, which I believe is fixed in 4.6 Patch 1 (due for release shortly.)
The DAT version information being missing is something different. Does it affect all machines running 8.8, or only some? If you send a "get full props" wakeup call to an affected machine, does it start reporting correctly?
