Trojan:INFOCARD - Alert for non-existent item? False positive?

[dhyre]

At login I now get a real-time protection blocked-item alert for:

Trojan.Agent/Gen-FakeAV[infoCard].Process

C:\Windows\Microsoft.NET\Framework\v3.0\Windows Communication Foundation\Infocard.exe

However, there is no such file when I look for it, and a scan of the NET folder with SAS, MBAM, and MSE all show no items of interest. This is with most recent update of program AND definitions on 05 Jan 2012. Seems to be a false positive to me, but thought I'd post it anyway. Anything I should do, or just wait for another update? Thanks.
