The first one is actually a file named Install751.exe that is carrying the Trojan.Fakealert-50 payload.
I should have remembered the adage: When all else fails, read the directions. After some problems with ClamXav, I read the directions. ClamXav CAN be tweaked to show the thin blue line and to quarantine bandits; you just have to use Preference BEFORE you make a selection of files to scan.
Therefore, I rescanned after tweaking Preferences. ClamXav sent the bogies to a file I named Quarantine. I emptied the trash and deleted the .exe file in Quarantine. Now, Gods in his heaven; alls right with the world. I can breathe easier now.
I appreciate you guys pointing me in the right direction.
