Hi not;
I've been trying to nail this one for months, getting closer but I've
updated manually already, so we'll see what happens this week.
Try this:

After much debugging, I have found that the problem with definition update
failures and repetition is because of an incorrect version of the file
gcUnCompress.dll in C:\WINDOWS\SYSTEM32\ (for XP) or C:\WINNT\SYSTEM32\
(for
2000 or systems upgraded from 2000).
The incorrect version is of length 130,272 bytes.
The correct version is of length 95,448 bytes.
To update your system to install the correct version of the file, do the
following:
1. In the System Notification Area, right-click on the MSAS icon and
select
"Shutdown Microsoft AntiSpyware".
2. In Explorer, navigate to C:\WINDOWS\SYSTEM32\, locate the file
"gcUnCompress.dll", right-click on it, and select "Delete".
3. In Control Panel "Add or Remove Programs", select "Microsoft
AntiSpyware"
and click button "Change".
4. Click "Next".
5. Select "Update Microsoft AntiSpyware", click "Next".
6. Click "Install".
7. When the re-installation finishes, click "Finish".
8. In Explorer, in folder C:\WINDOWS\SYSTEM32\, check that
"gcUnCompress.dll" is now 95,448 bytes long, by right-clicking it and
selecting "Properties".
9. Launch MSAS, pull down the File menu and select "Check for updates" -
this time it really will update your definition files to the latest
version.
10. In Explorer, open the folder C:\Program Files\Microsoft AntiSpyware,
and
satisfy yourself that the modification dates of the three definition files
have changed:
gcDeterminationData.gcd
gcThreatAuditThreatData.gcd
gcThreatAuditScanData.gcd
Done!
You won't ever have to manually install the definition files again, nor
will
the update keep repeating every time you try.

Please be sure to back up your computer before making changes - just in
case - but it worked great for me, with no problems. Hope this helps
someone with the same problem.
If you have no luck with the above... which I haven't... do a manual
update, at least until later this week when I try my own fix. Do not
worry about deleting gcUnCompress.dll, it will be reinstalled
automatically via the update MSAS.
Manual update:
Right click on MSAS icon within systray and choose Shutdown.
Goto these sites:
http://download.spynet.com/ASDefinitions/gcDeterminationData.gcd
http://download.spynet.com/ASDefinitions/gcThreatAuditScanData.gcd
http://download.spynet.com/ASDefinitions/gcThreatAuditThreatData.gcd
Save and overwrite if necessary these files to C:\Program files\Microsoft
Antispyware (or your favorite MSAS foldername)
Restart MSAS and "check for updates"
