Standard Shield under Pro 4.8-1201. Vista x86 sp1
« on: June 23, 2008, 06:36:10 PM »
At the moment all I have running is the standard shield.  I am only scanning executables.  Why then does Avast scan such files as .ico, .db, and index.dat to name a few?  The .ico are a few favicons in my TIF.  The db files are in my AppData.  As far as I know these are not executables?  I put them on the exclude list to no avail. 

What's the story?

You can reduce the protection (and increase performance) a little by disabling the open/created/modified files to be scanned into the Standard Shield settings.

That's the thing, I am not using any open/modify/creation resident scanning.  Strictly executable resident scanning.  Yet It scans non executable files.  I don't think it's all non executables, maybe just particular system stuff like index.dat.  I even see it scanning jpegs.

Another 'weird' occurrence is that I use Stardock's objectdock as my program launcher and I have an icon that contains shortcuts to my favorite programs.  When I click on the icon the real program executables get scanned when the list of programs appears on a drop down menu.  The programs are not being executed at this time.  What's up with this?

Sure seems that even though I do not have anything enabled except executables opens/modifies/creations are being scanned in some cases.

Here's some files that get scanned.  They tend to happen as i exit an application.  In this case it was IE7.

Do you mean you've edited these settings?

Those are the ones.  Everything is unchecked.

I get all kinds of files scanned.  I did manage to place a few on the exclude list and they do work.

Here are some more files being scanned by the resident scanner:

You're right, this is indeed reproducible here... We'll find out what the problem is, and fix it in the next program update.
BTW I _think_ it will be related to the new scanning mode introduced recently which takes care of scanning of "orphaned" memory-mapped files on close.

Thanks
