Spyware becomes increasingly malicious (let's return to reality)

Thu Jul 15 20:32:37 UTC 2004

The problem is Active-X, not the OS.  Anything running from the browser 
should be in a sandbox as it is with Java applications, the same is true 
for the email client.  Active-X gives scripts running from the browser 
and the email client access to the entire machine in the name of 
functionality.  In some cases users are prompte to authorize the 
installation of software when they get to a web page.  Even when they 
choose "No," the software continues to install.  Its a security hole big 
enough to drive a tank through.  Mozilla is your friend.
