secure-us.imrworldwide.com in Web Shield

[leftisthominid]

I have noticed that when I visit sites as Kotaku.com and fivethirtyeight.com, I get blue spikes from secure-us.imrworldwide.com. I was wondering, what is the deal with this. I have the site blocked by my router and Firefox does not allow cookies from that site. I was wondering what to do? Thanks.

imrworldwide.com is a domain used by Netratings Site Census which is an analytics company that is part of a network of sites, cookies, and other technologies used to track you, what you do and what you click on, as you go from site to site, surfing the Web.

I have been out of town for a week and I've noticed that there are some sites where it shows up on my desktop, but it is not showing up on my laptop. Any idea why this is?

Both computers are using Firefox and both computers reject third party cookies.

Do you have different anti-tracking add-ons between the two machines? 
Are you using the same browser on both computers? 
Any different security set-up between the two machines? 

Give us more information. Too much left unanswered.

OS?
Browser(s)?
Browser add-on(s)?
Security software on each machine?

Laptop uses Win7, Desktop uses Win8.1
Both use Firefox with tracking cookies rejected
Both use Noscript and avast extensions
-Laptop has WOT extension as well, while Desktop has Adblock Plus as well
Both use avast! IS and the free version of MBAM.

By router at school has secure-us.imrworldwide.com explicitly blocked. My parents router at home does not.

The sites I frequently see the secure-us.imrworldwide.com blue spikes on my desktop (e.g., fivethirtyeight.com, kotaku.com, gamefaqs.com) do not seem to show the same blue spikes on my parents house on my laptop. I won't be able to do an apples-to-apples comparison (i.e., connecting both my laptop and desktop to the same sites on the same network) until Sunday.

Take your time.
Also compare the settings in the software you have installed on both systems.

Could it be ISP related? I feel like I see different types of tracking sites showing up in the Web Shield that I am not used to seeing on my desktop?

Anyways, I did MBAM and avast! bootscans on my desktop before I came home, and nothing was ever found on my desktop.

(Also, my laptop has SpyBot, desktop doesn't)

I just got back home, both laptop and desktop show the same connections to secure-us.imrworldwide.com. Should I just presume that the reason it did not occur at my parents' house was simply due to ISP differences?

It could be that a ISP is blocking them while another one isn't.

It could be that a ISP is blocking them while another one isn't.

So I shouldn't have anything to worry about then, right?

I would block that site through the hosts file.

I would block that site through the hosts file.

How would I do that? (Also, my router blocks all connections to this website, so when the data leaves my computer it already goes nowhere) Thanks!
