Avast free
Program 7.0.1466  Virus database 120708-0 (won't update)
Windows XP media centre edition SP3
There is an old version of McAfee
Don't think I had any AV before avast, I've been using avast for years
I have had ongoing update problems.  I have rebooted the pc today with a clean boot so no 3rd party stuff loaded except avast, but it still won't update

Have you completely removed McAfee? you'll find there removal tool here http://singularlabs.com/uninstallers/security-software/ which you run after a normal uninstall then reboot, you might still have to run a repair of avast or even a clean install if it has been corrupted by leftovers of McAfee.

I'm only using the firewall in McAfee...the rest is not installed...do you think this could cause a problem? 

and McAfee did not start up with the clean boot but the update problem still exists..

As far as i knew McAfee's firewall comes with the antivirus as i dont see a standalone version of it, if the antivirus is installed but not active then it will still conflict with avast as there would still be active low level drivers running.
There are plenty of free standalone firewalls on the market if you require one, OutPost, Online Armor, Privatefirewall .

You need to remove McAfee altogether ( uninstall it ) then see if the problem persists, a repair or even a clean install of avast maybe required as McAfee could have corrupted it.

I just received a red avast warning that it could not update.  I followed the advice here (uninstalled, delated all files I could find, reinstalled, REbooted).  Now avast jsut sit and says its initializing and will not update.  I am running the free version on a HP laptop, AMD 4 core running Win7 Ult.  Can anyone help?

Their latest update seems to be broken. Dont worry, it'll be fixed.

I've just come to bump this myself  ;D

Same thing as GreyWulf has just happened.

I opened avast and tried updating there instead but got

"Last encountered error: Invalid file signature. Setup will terminate"

I don't think reinstall is the answer. I have 6 licenses and none of them will update.

HELP!

Just try a manual update, I suspect that it will report that it is up to date:
If so - Try a repair of avast:
Win7 - Control Panel, Programs & Features, uninstall a program, select 'avast! Anti-Virus,' click the Uninstall/Change and select Repair, click next and follow.

You may need to reboot after the repair.

This has in the past resolved this out of sync issue between reported and actual VPS version.
