@fudd777, you can install avast pro only with file-system shield (don't install all other shields) and then disable file-system shield and some virus database notifications. SafeZone is quite independent of other avast components.
@gautam7, bob3160 meant you should use PrtScr key and then e.g. MS Paint (with Ctrl+V) to paste the screenshot (i'm not really sure if it's blocked or not). However, this solution isn't suitable for everyone. Could you please try to define a folder in Exclusions (Sandbox -> Expert Settings -> Exclusions) and save those documents there? They should be excluded from virtualization. This will be fixed in avast7, sorry.
@NiveusLuna, I agree with you, but it's quite hard to do. Avast7 should use Chromium 15.x version (last known) and every time we get a Chromium build we have to do a lot of changes (add our DNS protection, disable a lot of components, plugins, etc). Since it's little automatized, we can't do that everytime when we release a new avast build (stand-alone SafeZone browser has approx. 30Mb and it's quite a lot for regular antivirus updates).
