Huh, seems I spoke too soon! Sorry!
(I was assuming the problem got simulated here because I saw the entries in the Error.log and Warning.log files - but these were in fact from YOUR machine
Never mind.
Anyway, your log files only indicate the problem on Nov 28th (yesterday) between 3:45pm and 9:02pm. So, I'm wondering... have you purged the logs? Or how come the first entry is from the 28th when you in fact started this thread on the 27th...
Also, is it possible that the problem started happening with the latest virus database? (released on Nov 26th).
Thanks
