Ah thank you.  RM mentioned that as well...my concern was that the date 
would get normalized, but I'll give it a go.  Thanks for the look to 
both of you :)  New rev here:

alert tcp $EXTERNAL_NET $HTTP_PORTS -> $HOME_NET any (msg:"MALWARE-CNC 
Win32/Asprox Variant Outbound Traffic"; flow:from_server, established; 
file_data; content:"|3c|html|3e 3c|body|3e|hi|21 3c 2f|body|3e 3c 
2f|html|3e|"; fast_pattern:only; 
reference:url,research.zscaler.com/2014/02/new-zbot-variant-goes-above-and-beyond.html; 
classtype:trojan-activity; sid:10000124; rev:2;)
