Well crap  , i guess this only works till i restart my PC , then i have to go thru the process of opening each folder again , so i guess it did not fix the problem completely :'(

okay,then you you might have an operating system issues ...
or: what view mode are you using when you open a folder containing pictures? list, thumbnail view? which one? could be that Windows is either rebuilding the thumbnails again and again or that you're not waiting long enough when you open a folder for all the thumbnails to be built and cached...and Avast is scanning that too.
I don't know which version of Windows you have...if you display a preview pane in folders or not (Vista/Seven). Anyway you can tweak the behavior in advanced settings/performance. What I mean is do you still have the same issue when displaying the pics just in list or detailed view? Are you using Windows Live Photo Gallery >>> it's a CPU hog on first use...just a few hints...

I am using XP SP3 and i put it on Thumbnail View , but it looks like a combination of Thumbnail and Tile view when i open a folder  , i have to go to the view and it will be on Thumbnail , but i have to change it to Tile , then back to Thumbnail for it to look like a normal thumbnail , but this is only after it loads everything which takes almost a minute  , there are Thumbs.db and ZbThumbnail.info icons in each folder , so it should load correctly  , and i use Windows Picture and Fax Viewer  as i dont like the way Windows Live looks

But every time i open  the Avast Icon is spinning in the taskbar , that is why i feel it is Avast doing it

What else could it be making it re-load ??

I have done a Scandisk , and the issue is the same so if it was i Windows Issue then that should have fixed it i would think

I don't have the ZbThumbnail.info on any of my image folders, I have done a google search on that file and some say it is related to Cannon, http://www.dcresource.com/forums/showthread.php?t=9963 and http://www.tomshardware.com/forum/34547-5-what-zbthumbnail-info.

So it may be that this file when you open the folder actually checks the images files against its information for new additions/deletions, etc. and this may cause avast to scan the files that it accesses.

I have many image folders in many of then I have also deleted the thumbs.db as I don't want the database updated as my system can display the folder thumbnails quickly.

Yes i use a Canon camera so that would be the ZbThumbnail  , but that is not in every picture folder , just some of them so i dont think that should be any problem

But i would still like to know how i can stop Avast from scanning my picture folders EVERY time   , as that still seems to be the issue causing the delayed loading

I just tried setting Exclusions on scanning that is supposed to stop it from scaning those folders anytime and it still scans the folder when i open them after telling it not to scan my pictures folder  , so why is it still scanning ??

it says "Exclusions will apply to both on demand scans and to real time shields"  

But it still scans the folders i checked to not scan

First, it isn't normal behaviour (default action for file system shield) for avast to scan the folders contents when you open it. avast is an 'on-access' scanner so something is accessing those files to cause avast to scan the contents. That is why I mentioned the ZbThumbnail.info as I don't know what that is meant to do as I don't have a Cannon camera nor the software to see what it does.

So that is the quandary, as avast doesn't initiate scans, but reacts to something accessing the file or you have changed the default settings in the file system shield (and I believe you said that you hadn't in an earlier post).

Second, what Exclusions did you use as the avast Settings, Exclusions are effectively for the on-demand scan and these are being scanned by the on-access scanner (file system shield, expert settings, exclusions).

However, I wouldn't advise excluding complete folders or just file types (e.g. *.jpg) within a folder as there are image file types , which can be exploited/infected so they should be scanned on-access.

Whilst doing this I have opened 17 image folders/sub-folders and the file system shield started with an activity count of 822 ending 939. There are many hundreds (I didn't count them) of images in those folders and only on the odd occasion did avast actually scan a file in the folders, one time it scanned a thumbs.db file that it left behind.

Most of the files scanned were through my use of image capture software to grab some basic images (the creation of a new file, etc.) and only a few images were actually scanned outside of that, why I don't know as I wasn't physically accessing a file in the folder/s. So it is still a mystery to me why it is scanning your files.

Maybe i should be more informative  , i do not mean thea Avast is poping up with a "Scan" page  , what i am meaning is that every time i open a picture folder , the Icon in the taskbar starts spinning like it is alerted to something (like it does when you open a web page) , and the entire time the Icon is spinning the window(open folder) is blank , then when it stops spinning (up to 1 minute depending on the number of pictures in the folder) the page finally loads 

So to me it is Scanning when i open the folder and it seems to be stopping anything from loading until it stops scanning or whatever it is doing

Does that make more sense ??

I understand the problem, I just can't understand why it is happening.

My images aren't scan pages and that wasn't what I thought was happening for you. The purpose of the images was to show the current scan count (file system shield, info) before opening any of 17 image folders, with a couple of images during that time and one at the end to show it wasn't scanning all my images.

So that behaviour isn't happening on my system and I really can see how it is happening on your system as you say you haven't changed any default settings and avast doesn't scan files of its own accord. So something has to be accessing those files in the image folders you open, what that is, is the big question.

My only thought was what created the ZbThumbnail.info file and what that might do when a folder is opened, but then you say that it isn't in all folders, so there we have inconsistency as if it were that then presumably it wouldn't cause avast to scan in folders where there was no ZbThumbnail.info file.

So I'm really at a loss as to what might be causing this.

Could it be that avast! is scanning the thumbnail cache, as stuff is written/created?

Everytime I open a picture folder, it is being scanned.

If you open avast! and go to the file system shield, and then look at the 'Last file scanned:' what is being scanned?

Update :

I just tried something and it seems to have fixed the problem at least for now

The problem seems to have been Adobe Photoshop 7 , not Avast as far as i can tell the issue was fixed by going to any photo and right clicking and going to Properties , then under the Adobe tab , uncheck Generate Thumbnail  , i had never had this issue before so i dont know what caused it to do this , but so far it seems to have solved the issue  , i still dont know why Avast still scans or whatever its doing , but for now the speed of loading  pictures is working normally again !!

Well as I said avast doesn't scan of its own accord, so all I can think of is that Adobe Photoshop is converting the file to display a thumbnail image and that would force avast to scan it. Windows already has a Thumbnail option in the View menu list (I use this in my image folders and that doesn't force avast to scan), so no need to have another program convert to thumbnails.

Happy that you have finally got to the bottom of this mystery.
