I am not too sure…i was searching off on google and got to a link from some site to hxtp://www.couponso.net/?subid=178775&subid2=191461
and this was blocked by avast network shield 
Is this a FP ??? i love modern warfare games…
Nothing showed up on VT…
You should know the drill…
More info…what does the avast warning say…screenshot?
Have you tested the url with sucuri and zulu…urlquery
http://zulu.zscaler.com/submission/show/daedcf3cc8f61e2b04fe7c30667e2b84-1340779932
securi says invalid site adress
when using sucuri you only scan the domain…
and then you get this
http://sitecheck.sucuri.net/results/www.couponso.net/
looks like a phishing attempt :-X
Thanks!..also i didnt notice the red alert by WOT see: http://www.mywot.com/en/scorecard/www.couponso.net
also see the list of IP warnings at the bottom here
Thanks! that does seem malicious 
Hi Pondus & true indian,
Verdict simple not malicious as such but functioning as a known scam website.
There is also a script that is going to clients dot bluecava.com/data?p=D440F31E-EDE7-4BB2-B328-527A10AB7572 …
with a n accompanying promotional iPad gift scam with an IMG SRC lander script …
Mentioned in the malicious hidden 0-0-0 iFrames here by Sucuri’s: http://sitecheck.sucuri.net/results/www.couponso.net/
bluecava dot com is known for unknown_html_RFI_eval malcode (most of the malware from that IP, 216.23.166.114, has been closed or is dead now),
but as a scam site still active and flagged. See: http://www.mywot.com/en/scorecard/clients.bluecava.com?utm_source=addon&utm_content=popup-donuts
Main site is flagged here for security issues: http://www.siteadvisor.com/sites/couponso.net
I reported site as scam site at zulu zscaler feed-back,
polonus
Nice explanation…thanks Pol 
You can also use common sense.
Would a regular gaming site’s home page have a long string like subid=178775&subid2=191461 attached to it? Is it common to have an official game with the .net domain?
