Spyware, viruses, & security : Steady State v Malware updates on PACs

Steady State v Malware updates on PACs

Am a non-geek administrator of small network of Public Access Computers. Tech help is over two hundred miles away and even further budget-wise.

Having problems with kids and their 'toons/games loading the PACs up with spyware. Would like to try Microsoft Steady State as a means of keeping the machines humming the way I set them up as opposed to what the bored 12 year-olds want. It just makes my job easier if the machines stay the way I set them up. We don't have money in the budget for real tech help.

Anywho, was told SteadyState wouldn't allow for automatic updates of my AVG malware/virus protection. So, how would I go about doing daily AVG updates if I put Steady State on the computers?

Would I have to daily reconfigure the Steady State too? How involved is that? I only get 20 hours a week and trying to run a small library with that time. I really don't have hours a week to spend on computer maintenance. Need some easy to handle methods. Am married to the AVG until March 2010. Thinking of switching to vipre at that time.

The AVG does seem to catch stuff, but kids come in after update/computer tests and sometimes they borrow trouble for me. And I want to make sure all patron info/changes are scrubbed at close of day.

Thanks for any help, oh great gurus of cnet!
