I’m not sure that it will have been installed correctly in safe mode (could well be wrong) did you try to update it from safe mode?

On the install from safe mode perhaps the registry key HKLM\SYSTEM\CurrentControlSet\Services\avastTestService doesn’t have read access rights to all only ‘The Administrator’ not those with administrator rights, you could check that.

Failing that I suggest you download the latest version 4.6.744 and save it to your HDD boot into safe mode and uninstall avast, reboot and install the latest version using ‘The Administrator’ account not just an account with admin rights and reboot.

From your log it looks like you have an old version 229.12.2005 12:26:49 general: Running setup_av_pro-28c (652)"

avast can’t be installed in Safe Mode as the Windows Installer service cannot run for installations at Safe Mode.
On contrary, avast could be uninstalled at Safe Mode.

Is there more than one account with Administrator rights?
