Spysweeper turned this up on my system too. A Google search for the trojan name found an indication that this is a false positive from Spysweeper. See the thread at http://en.community.dell.com/forums/.../19496660.aspx
for more info.
A poster on that forum also gave the Webroot customer support phone number and hours:
866-612-4268 option # 5 for tech support. If you don`t have your license number available, give them your email address.
They are available Monday through Friday 9:00 am to 8:00 pm Eastern time, Saturday 11:00 to 7:00 pm, Sunday 11:00 to 6:00 pm.
I'm planning to call them to confirm. . .
