Not unless you read up on Internet security.

How Stuff Works - Security Channel (http://computer.howstuffworks.com/security-channel.htm)

Software such as Firewalls (http://computer.howstuffworks.com/firewall.htm) can block incoming and outgoing connections.

One way to check if something is odd (unless you are really clued up on Net Security it won't be much help on it's own) is to use a certain MS-DOS function.

Click on Start > Run and type in "Netstat 5" (without the quotes)

This shows exactly what addresses are bing sent and recieved on your computer. Currently on this PC I'm getting:

TCP     [my IP address]     www.computerhope.com:80     TIME_WAIT

If there is someone lurking, you may get something similar, except instead of computerhope.com, you'll get a strange looking IP address (simply a load of apparently meaningless numbers, for example 1.160.10.240) and the words "CONNECTION_ESTABLISHED".

Be sure not to load up any webpages though, because this will have a similar effect as if a cracker was lurking!

Bill2004.....When you say monitoring ....do you mean from an external source or did you mean from an internal source....  I believed Both Corrosive , Raptor and Merlin have given you some leads.....but if its someone in your own household ....they could have installed a key logger to monitor your activities ......

Hope this helps you.

I wouldn't quite trust a partner that's spying on me.. But to each his own.

Bill2004.....Well , if you have complete access to the network .....I would look at all the programs in the Windows program files......look for some odd program name .....theres one called antispy.....which does that.
do a google search for keyloggers......you will be amazed at how many there are . If you see an app which you dont recognize do a google search to find out what it is ......but dont do it on your work pc.......and somewhere else on your pc there will be a file with all the activities . It is generated by the spy program.(keylogger)
Something else you might do as well if you can is to delete all your history and temp internet files every day just before you go home.

Hope this helps you .

From that list, I cannot tell that there is someone 'monitoring' your computer.

Are you certain it's not spyware you're after..

I take it that was a browser Window you had open?

check and see if remote access is enabled?check to see if a program called radmin is listed on one of those pcs...and have you add any of this things happen >CD-ROM drive opens at random times
Wave (.wav) files play for no reason
Strange dialog boxes appear
Internet downloads are slow
Files appear or disappear

I suggest you use an IP scanner to see where all the IP entries are from.

NeoTrace Express 3.25 (http://www.networkingfiles.com/PingFinger/Neotraceexpress.htm) is a freeware version.
