Avast! Crash/Error Report

I just formatted my computer with a copy of XP 64. After installing Avast I restarted my computer, the first few times Avast started regularly, however the last 3 times I have received a Microsoft Error Report regarding the “Avast! antivirus Update.” The report contains

Error Signature:
szAppName : avast.setup szAppVer : 8.0.1483.72 szModName : ntdll.dll
szModVer : 5.2.3790.4937 offset : 0004f0f3

Are there specific steps to take to prevent future errors such as this upon boot.
