Old VLC was marked suspect

Avast flagged up VLC as suspect and offered to run it in a sandbox. I had been using the program for a long time but this is the first Avast warning I’ve seen. Upgrading VLC from 1.0.0 to 1.1.11 seems to have cleared things up.

Avast 6.0.1289 with 111124-0
Vista Home Premium SP2

Maybe they consider VLC 1.0.0 a security risk…since it is 18 updates behind ???
