When I did a Google search I came up with it being Spyware:

Process File: sahagent or sahagent.exe
Process Name: Sahagent
Description: Application collects and combines user's
                   Internet browsing behaviour and sends it to
                   ShopAtHomeSelect servers.
Company: ShopAtHomeSelect.com
Security Risk ( Virus/Trojan/Worm/Adware/Spyware ): Yes

I use Spybot Search and Destroy to keep my system clean:

You could probably do a Google.com search and find
more info.

I selected an address under contact in Outlook 2000 and
got this above error message. Does anyone what these mean
and the fix? Thank in advance.
