Why are Second Life viewers only working in Avast's Sandbox mode?

[Mokymok Beck]

Hello there,

I'm on Windows 7 64bits.

I recently started having rather strange issues running Second Life viewers. I have tried the official Second Life viewer, Firestorm, and a couple of other third party viewers that were shown on the third party viewer directory page,

Just a few days prior to this happening, any and all viewers were working just fine. Nothing in my computer has been changed and all of my drivers are up to date.

 

I try to run a viewer, and it only shows the usual "Loading Firestorm" or "Loading Second Life" window and then immediately shuts down without actually showing the log in screen.

 

I have discovered that this doesn't happen when I run the viewers through Avast's Sandbox; I can roam Second Life just fine, except I cannot save any of my settings and/or have a SL cache due to being run in Avast Sandbox. Disabling Avast and all other firewalls prior to launching the viewers doesn't fix the issue.

 

Is there a way to make it so the viewers do not have to be run exclusively in Avast Sandbox mode?

Perhaps you or another user of your PC has changed something?

I use the latest version of Avast and do not have this issue with any viewer.

Check the application settings for the viewer .exe's, slvoice.exe, and other critical assets.
