Today I upgraded to latest version of Avast.
I then tried to use a program called "1st page 2000 by Eversoft", this is a program I have been using for around 10 years on a weekly basis.
Avast now prompts whether or not to sandbox it:-
I selected yes first of all to see what it would do, my PC hung.
I rebooted and this time selected no, my PC hung again.
I rebooted and this time turned off sandboxing completely, ran the program and my PC hung.
Reeboted again turned on sandboxing, disabled Avast, all OK. I then came out of the program, renabled avast, re-ran the program. Still OK.
I restored a Ghost image of my machine take prior to Avast upgrade, all ran OK.
Upgraded Avast problems returned.
In Summary, it would appear that Sandboxing/Avast 6.0 have some issues and the solution to my problem is not to turn off/on Sandboxing but to disable Avast, start the program, exit the program, restart Avast re-run program. All is then well until reboot.
