system calling website

Hi all - I'm guessing that this is the right folder -

I'm getting odd AVG warnings - generally when I come out of standby. AVG box tells me that system is trying to connect to 72.3.136.211 via TCP. This started happening this afternoon. In the AVG log, the alerts come in 4 pairs - each pair says remote address 72.3.136.211.80 - but there'll be one of them with local address "localhost:2068" and the other "localhost:2065". This IP seems to be connected with "seeds.adgardener.com". From whois, I get

Rackspace.com, Ltd. RSCP-NET-4 (NET-72-3-128-0-1)
72.3.128.0 - 72.3.255.255
Mooner Ent RSPC-58539-1108011713 (NET-72-3-136-208-1)
72.3.136.208 - 72.3.136.223

Adgardener seem to do stuff with or for drudgereport.com, which I do frequent. Not much else out there about it.

Help?
