At first I thought it was a NoScript issue, but now I just confused .
Separately, 188.8.131.52 looks to not like Microsoft. (Understandable.)
URL: Microsoft Security Essentials Beta - http://www.microsoft.com/security_essentials/
This one may be a bit tough for you (try proxy), but other should be able to confirm?
With 184.108.40.206, I (living in the USA) am redirected to http://www.microsoft.com/security_essentials/market.aspx which states:

No cookie is being set. (What would be set is, mkt=en-us.)
220.127.116.11 works. Or maybe it doesn't? I'm totally confused on this one.
In a different Profile, with (I thought it was) 18.104.22.168, things worked correctly?
But now I'm being redirected - even with NoScript disabled?
SeaMonkey 1.1.17 & NoScript 22.214.171.124 are working.
SeaMonkey 1.1.17 & NoScript 126.96.36.199 are working.
FF 3.0.10 & NoScript 188.8.131.52 are working.
Gecko/20090206 Minefield/3.2a1pre & NoScript 184.108.40.206 are working.
I know it worked at least once in SeaMonkey 2?
I totally wacked on this one - splitting ?
