Windows 7 64bit, when i run the viewer and Security Essentials does a scan (of the running process), it detects the viewer.exe as a Trojan virus (Trojan:Win32/Rundas!plock)
Yes, we are aware of that. It was reported in this thread and some tickets. We are in conversation with Microsoft - they are responsive but looks like the issue is back after yesterday's successful attempt to eliminate it.
We'll keep trying to make Microsoft resolve this asap. Sorry for any inconvenience.
