Got something to add to my own Reply#112.
I tested the functions of the On-Access Standard Shield protection:
Here are the test results:
================
1. Standard resident shield DOES scan both online(or locally cached) and locally saved web pages
Avast! Home scanned locally saved web pages as well as online pages on "High"(or "Custom" for all file types instead of defaults) settings w/wo Web Shield started.
As I stated before, it scans all temporary internet files which are either freshly downloaded from the web or reloaded from the local directory if not expired.
2. Standard resident shield DID carry out script blocking on certain operations as I had set up so.
Avast! Home successfully blocked my test scripts, not Javascripts though, to create files(open for writing) or to delete files as I had specified in the "Blocked Operations" in [Blocker] tab.
When I disabled certain script blocking functions such as Open-file-for-writing or Deleting-file, my test scripts then had the latitude.
Yet, I haven't found a way to test the extra layers of protection provided by Avast! Home's Web Shield or Avast! PRO Script Blocker.
More explicitly, I still don't know the functional difference w/wo Script Blocker other than the possible counter-measures against the memory-bound MSDE SQL slammer. For now I don't even have MSDE on hand to worry about or to test with though. If someone can show me other differences from the spec, I might try to download and test out Avast! PRO.
I wonder if this thread will ever reach a conclusion dialectically or empirically to solve the mystery.
