I have been using avast free on my xp and 7 machines.
The program works great, but with the version 7 which it automatically 
updates to, the interface has gone silent.
I wonder what free anti-virus programs are people using instead of avast? 
It seems to be much more thorough than Microsoft Security Essentials or AVG.
