Our network has an ePO server pushing current DATs, SPs, for VirusScan Enterprise 8.7i SP3. Windows WSUS server pushing current Windows updates. Large numbers of machine suddenly began rebooting with DCOM server process launcher errors. McAfee detects svchost.exe as infected with Wecorl.a

This virus/trojan is fairly old and should have been caught, unless some new exploit is able to drop it without McAfee Virus reacting to it. Anyone else seeing this?
