How to disable boot scan

After 60 days’ use i’ve just had to enter a new registration key. Going through the settings I inadvertently enabled scan at boot up. Now others are complaining at how long the computer takes to start up and would prefer to scan on demand only as we had it before. I couldn’t see how to disable the boot scan setting. Using Avast4.6Home on Windows 2000.

The boot-time scan should be performed only once and automatically unscheduled - i.e. it should be started on the next boot unless you schedule it again manually.
So, you are saying that you can see avast! scanner starting every boot?

Here are the direction on performing a boot time scan if you follow this procedure you may be

able to discover why a scan is being performed at each boot and alter accordingly

Scheduling the Boot Time Scan

Click on the Menu button.
Choose Schedule Boot Time Scan.
Doing so displays a dialog allowing you to schedule virus scanning.
Check Archives, if you want scan all the archives.
Specify whether all the disks or just a specific folder should be scanned.
Select Advanced options for scheduling details.
Select how to automatically process infected files.
Choose how to automatically process infected system files.
Click the Schedule button to confirm the settings.

Thanks to all for your help. I should have checked better before I posted. The boot scan was after all just that first time when restarting after inserting the new registration key.

I just couldn’t recall Avast doing that when first installed from scratch so thought I had changed some setting that made it happen, and that it would in future happen every time the computer was booted up.
