Hello BuBbly01:
Yes... your computer is just fine. I thought somehow I messed up my XP Pro machine or some of my Avast4Home files were corrupted.
But that is not the case.
There is an issue with the initialization of the scanning engine when you try to run a Boot Time Scan.
When the boot time scan fails... all that will happen is it will bypass the boot time scan screen and leave you at the login prompt for NT/2000/XP.
There is supposed to be a new PROGRAM release this week to address the issue. So all that you will have to do is download the entire program file through "auto-update" and then restart the PC.
The boot time scan should THEN work.
Were all waiting patiently for a fix. There has been no new program update yet for avast. The only updates there have been are the VPS updates that include newly discovered viruses.
We're not waiting for a VPS fix....but a PROGRAM fix.
There is nothing wrong with your PC... it's just a bug in the scanning engine.
Keep checking this thread for updates on the issue!
And welcome to the forums BuBbly01!
