Any other solution for stick then?

Hi there,
we are roaming a lot with our USB-sticks (office, home, customers) and would like to check the environment before we start any application. Is there any current product from Avast which can do that? I searched the website and shop in vain.

(We are running several sticks with mail and banking applications on them, some are still U3-sticks equipped with the discontinued Avast-U3-edition where the antivirus files are no longer updated.)

Has anyone a good idea how to reach our goal with Avast?
Thanks in advance!
Mike
