This may seem like a basic question but I have to ask.

As a single user of my own PC and laptop I've never had reason to ask this.

When a PC is set up with multiple accounts, one being admin and the others limited, when you use/install a program such as SpyBot or AdAware will it work on all accounts?

The scenario is this: My friend has five kids, they have one PC. Mom is admin, the kids all have limited accounts. When Kasperskys AV, AdAware, SpyBot, CCleaner and Spyware Blaster are installed, do the programs have to be installed in ALL accounts? I believe KAV covers all accounts-the entire PC. The others I just don't know!

When my question is answered, I may have part two!

Thanks, and sorry if this a dumb question.
