Cookies, Imrworldwide, and Nielsen Netratings: What's the Connection?
This morning while running SPYSWEEPER on my computer I discovered (and then quarantined) a cookie named “imrworldwide.com.” On doing some research I found that typing in the URL “www.imrworldwide.com” into my browser switched me immediately to “www.nielsen-netratings.com.” But I can find no reference on the Nielsen site to this cookie.
I then find this cookie might be associated with an Australian entity named “redsheriff.com” that has been linked (I use the phrase “has been linked” intentionally to indicate I don’t really know if any of this is true) with spyware that may send data on personal web surfing behavior to a server application; use of this system has been linked publicly with organizations such as the BBC.
How concerned should I be about this type of spyware? I run SPYSWEEPER once per week. Should I be doing this more frequently?
