I've been following this Subject since the 25th of this month because I had the Shield problem here on this Wn764bit sys.
I downloaded the patch files on the 25th and replaced both of them in my Avast folder ... as outlined in prior instructions. I did that while I having the Shield turned off, browsers closed and if I remember correctly, I had to close out Google talk.
Once the replacement was completed I turned the Shield back on in Avast settings and then started Firefox up...
From what I've seen so far is that the Script Shield is running in Avast and after a few hours of browsing I noticed that the counter in the Real Time Shields display of Avast displayed zero for both numbers. So, thinking that maybe my NoScript was doing too well, I opened up a profile that has no extensions installed and then browsed around some... checked that counter and it was still zero for both counters.
Then I figured I'd start up IE and visit the same sites that I did with Firefox and the first scan number immediately went off zero... I did some more and it increased again... I closed IE, went back to Firefox (no extensions) and visited those same sites... the counter did not increment.
So, I know people here have gotten the scanning working... have you actually notice if the counter goes up as you are using Firefox?
Thanks.
Edit
I have portable Chrome and here Firefox 3.28 and I started them up...
The counters for the older Firefox incremented when I visited a site.
The counters for the latest Chrome did not increment after visiting the same site.

OK... what I did. Even knowing that I downloaded those two files on the 25th and moved them into the Avast folder (the dates in my file explore for those two files were also dated the 25th so, I knew that they were the new ones... plus with those new files I could turn on the script scanning option in avast (though the counters did not move as stated above) ... where prior to having those new files in avast... an attempt to turn it on responded with an error...
Anyway, I decided to start fresh with all this ... closed down browsers, closed down my Google talk (which I found had those two file open), stopped the monitoring in avast, deleted the old (new ones that I got from here) and replaced them with the two downloaded files again.. plus I installed those two .sum files.
Anyway, to my surprise... everything seems to be working properly now... I have no clue why it didn't work the first time...
So, all is OK not... and thanks for the great board and software!
