I voluntarily do not run LS at work because I know that if something would happen, I'd be in trouble, more or less. It's not like I would be fired but the stuff installed is somewhat old and valuable and I would have a hard time setting it up again. Don't want to risk that.

However, theratening to unplug someone from the network for installing LS sounds like the netrep is ignorant, nothing more. A bit like my dad who had a superficial fear of NICs before we demonstrated how handy it was for each machine to access each others resources.
And besides, if working in a big companu, why not install a decent browser for the people you're watching over - then there would be no popups to click. Or to just tell them simple facts about adware and spyware. I refuse to believe that humans cannot learn.
