Vista wont boot after avast install

[drahyrt]

Hi,
Just installed AVAST! , and now the vista machine won't boot paste the microsoft black page with the box and dots streaming across it.

It will boot in safe mode. I have tried uninstalling and reinstalling, and uninstalling altogether, but appears only safe mode will work.
I did reinstall AVAST after uninstall, and did a boot scan and it booted, but it froze after an hour and when turned on it stalled in the same place as before again. :'(

It looks like I will have to use backup strategies, which is a problem because it means I may lose some settings etc.

Any help appreciated.

Hello drahyrt welcome to the Avast forum
Did you have a Anti-virus installed prior to Avast?
If so, what was the name of the AV program?
How was it removed from your system?
Many AV programs have additional removal tools available in addition to the usual Add/Remove.

Computer associates spy and av was installed and removed with windows uninstall. Which does not have "removal" options. Have tried uninstalling avast but only in safe mode as regular mode won't run again.

Thanks

Which firewall do you use?
If you're not being able to boot after installing avast, something is conflicting with it. Maybe not well removed CA programs.
