no one is supposed to use it for internet access, however, i have teenagers helping me out and sure enough, i look at the history and they're been on it.
Then you should call them on it. Since this is a business machine this could very well damage your business. When you are going to other, NECESSARY sites for the business on an infected computer there is a possibility of spreading these infections to others. This would definitely damage your business because there is a chance others could trace these infections back to your machine.
One free program can offer some help to you, and I would never run a computer without it, that is
SpywareBlaster. It is FREE, it DOES NOT run in the background but it DOES protect the computer against the following;
ActiveX-based spyware, adware, browser hijackers, dialers, and other potentially unwanted software.
Block spyware/tracking cookies in Internet Explorer and Mozilla Firefox.
Restrict the actions of potentially unwanted sites in Internet Explorer.
All you need to do is download it, install it and update it and then enable all the protection. Update it at least weekly and then enable the new items on the update.
You also should set you Internet Explorer security settings higher, you will have to experiment with that to be certain that your business necessities are not blocked but that shouldn't take you long to figure out the proper higher setting. Also you need to Internet Explorer to accept 1st party cookies and block all 3rd party cookies.

One thing you can also do, you say you can tell by the history what sites these kids are surfing to...check daily and block each one they have visited each day. Sooner or later the only ones left which can be viewed will only be those you need for your business. It may be tedious but it is a way to make their surfing very difficult.

Now you also said
internet exploder browser. it utilizes pop-ups.
You can also block pop-ups with IE and also set which sites will allow pop-ups and which site will block pop ups.

Also, you say you would prefer to use firefox, as do I...is the reason you cannot is because this Teetime software MUST be used with IE? Because Firefox can also be set to allow pop-ups from specific sites and block them from others.
