If you have administrative access on your machine and you're comfortable monkeying around under the hood, the easiest way is to rid yourself of these nuisances is to block them in your hosts file. In Mac: open terminal and type /etc/hosts and then enter the following line (this should be all on one line, just in case the line breaks here):

127.0.0.1 tcr.tynt.com intellitxt.com vibrantmedia.com kona.kontera.com blippr.com www.blippr.com

Then save and close that file. When you save it, you'll be asked for an administrator password.

On a windows machine the process will be similar- I don't know what operating system you're using at work, but here is an example of instructions for modifying your hosts file on Vista.

So what's happening here is that these companies (Tynt, Intellitxt, etc.) offer these annoying "services" to websites.  They say, "put this script on your website. Your visitors will love it, and any time anyone clicks these bubbles, we'll give you a tenth of a penny!"

And then the guy running the website puts something in the code of his site that looks like this:

<script src="http://tcr.tynt.com/javascripts/tracer.js"></script>

What you're doing is telling your computer to look only on your local machine (127.0.0.1) instead of the internet for anything coming from that list of websites.  Since those websites don't exist on your local machine, the web page won't be able to find that annoying script.

If you're not comfortable monkeying around under the hood or you don't have internet access, you may be able to find a javascript blocker plugin for your browser that accomplishes the same thing.

For IE: I haven't seen anything useful for Internet Explorer, unfortunately, and you're better off using Chrome or Firefox if it's possible.  Any IE people know of useful tools here?

I hate those too. I found this answer through Google, not Bing :)

"If you use Internet Explorer 7 (IE7): Download and install the free IE7Pro enhancement for IE7. It has lots of features to extend the capabilities of IE7, but you want to choose "Ad Blocker" from the IE7Pro preferences. Then simply select filter type "URL block filter" and add intellitxt.com and vibrantmedia.com to the rules.

Opera users can use the filtering built into the browser. Open tools / advanced / blocked content and add http://*.*.intellitxt.com/* and you're done.

All you need if you're running Firefox is a simple add-on. Download and install the Adblock plus add on for Firefox. It's easy. Go to Tools / add-ons, then click on Get Add-ons in the pop up window. Search for and install Adblock plus. You'll have to exit Firefox and reload for Adblock plus to run. If you want to block all ads, you can choose a subscription. If you're only interested in blocking intellitxt, simply go to preferences, click add a filter and enter *.intellitxt.*"

Because, as Jay says, these aggravations are being inflicted on you by the particular site you see them on, you could do worse than registering your contempt with the appropriate authorities, and where possible, finding a better class of site on which to spend your time.
