Windows wont start after installing AVG Antivirus 8

[Helen]

I installed AVG Antivirus 8 and it said it had installed successfully, but
then the computer shutdaown because it said there was a problem.
When I tried to start it up again it would not start windows. It eventually
comes up with a message that the hal.dll file in windows 32 is missing or
corrupted and to reinstal it.
I tried to start windows in safe mode and also the last known successful
starup but neither works.
I have tried to start with the windows cd to do a repair but I cant get it
to start from the cd either.
Please help..

I discovered my ASUS MB would not boot from a multi-drive (DVD-CD),
ONLY from a real CD only drive. That might explain your inability to
boot from your XP CD.
