over the Internet.

To pepper Internet users with its solicitations, the HerbalKing group 
used a botnet, a global network of computers infected with malicious 
software, often without the knowledge of their owners.

The security firm Marshal Software, which assisted the F.T.C. with the 
investigation, estimated in court documents that the group.s Mega-D 
botnet - named after one of its pill products - was made up of 35,000
