Instead of adding a new topic I thought I'd add comments here. A friend sent me a link to read regarding personal use of your work computer.

Obviously, I use my work computer to surf online, chat with friends, etc. I have used Yahoo! Messenger for the past 4 years here at work. It is also used by many other employees at my corporation (unofficially). Of course I watch where I go and who I talk to, but I find it useful instead of picking up the phone and calling for small problems or questions. It has also saved me on days that are incredibly slow when chatting with friends. Yahoo seems to be the only messenger that works through our firewalls and is easy to troubleshoot when problems arise.
This news article was interesting to me. Should the people at work who are in violation of company policy using IM consider going this far and buy these protective devices?
