Final Update: VPS 080705-0 seems to have fixed this false positive (at least for me)
Details:
I didn't have time this morning (Japan time) to go and check the problem again by disabling my workaround. Symantec's subscription checker is notorious for crapping out (it IS a virus as far as I am concerned), but since I do need to use Norton Ghost sometimes, I am basically restoring an backup disk image every time my Symantec "subscription" craps out. This false positive "symlcsv1.exe" created that situation, so I had to go back to a previous backup and restore my disk image (ironically by using Ghost).
VPS 080704-2, which was the virus definition file of my backup still gives multiple (in excess of 10-15) virus popups for this, but the current, updated VPS 080705-0 doesn't do this anymore under the same configuration. Fast work by Avast, thank you! As far as I can tell, this issue is fixed.
@DavidR: Thanks for the Log Viewer hint .... it didn't really work for me in this case, though, because every time the Symantec subscription service crapped out, I had to keep going back to a known good disk image, which also erased my log, of course.
