An old thread, I know.
I picked up the tutorial last night on bleeping, set it up and it works.
It didn't seem to make much sense to schedule a scan every night, on the other hand it doesn't make much sense to stay exposed to new virii for several hours after an update.
I don't know if this could be done with the Windows scheduler at the time that this thread was started, but in Vista 64 bit it is not only possible - but for me it worked the first time (-:
Basically do everything listed in the original post, as always there are SLIGHT name changes in a FEW places with this later version of Windows.
In the left panel click on the Task Scheduler Library tab.
Find your scheduled task in the middle panel and right click on it, select properties.
In the properties window that pops up click on the Triggers tab.
Your existing scheduled scan should show in the big panel.
Click on New at the bottom left corner, a New Trigger window should pop up.
In the top drop down list choose "On an event".
In the Settings panel choose Custom, then click Edit Event Filter.
Be sure you are on the Filter tab.
In the Logged drop down list select Anytime.
From Event Level select Information.
Select By Source and in the Event Sources drop down select BOTH Application Popup and avast!
Leave everything else alone on this window, click OK to close.
This should take you back to the Edit trigger window, be sure Enabled is checked in the bottom left corner, then click OK to close.
That should take you back to the Properties window and you should see your new "On an event" trigger in the main panel.
Basically what this does is to set up a scan to run as soon as Avast sends an informational message and the only ones I ever get are "Virus database has been updated".
MY goal is to run a scan as soon as possible after Avast issues an update.
OK, but that is just the triggering of WHEN to run the scan.
You still need to fill in the Actions tab the same way you did for your scheduled scan.
Reminder;
Click on the Actions tab, click on New in the bottom left corner, fill in the window that pops up in the same way that you did for the scheduled run.
e.g. browse to "C:\Program Files\Alwil Software\Avast4\ashQuick.exe" (or wherever) and fill in C: D: in the arguments box.
TESTING;
Keep your sound volume at a level where you will hear it, e.g. be sure it isn't muted.
When you hear the DAILY "Virus database has been updated" message look for a new avast scan window.
You will know it is new if only a few files have been scanned.
At some point you might as well delete the (daily, weekly, monthly, etc) scheduled task.
