I will try this. This situation, though, is fast changing with many
variations. Last night the tones ....- ....- ....- on and on were heard very
faint while I was sleeping. Also, last evening I clearly heard an audible
constant hum that accompanied the fridge turn-on cycle that was not related
to its operational 'normal' hum. Then, I hear clicking sounds in the walls
at night (do not seem to be from the neighbor's home, but in the walls).
Also, the temperature regulation is still there. One section in the house,
~4 feet from a window seems to be a few degrees higher (63 deg F) than the
middle of the room (60 deg F) or the outside (55 deg F). This does not make
sense because it stays the same even when I am not in the area; there is no
heat source in the area (only a recessed overhead light fixture, etc. - all
turned off). The old 70 deg F accurate regulation is now gone.
< Since my system is now being monitored by some external agent ( I can see
that someone has started processes - dllhost.exe, tftp.exe - two of them,
cmd.exe) at the moment, I will be logging off now; will continue later. I
have already informed the ISP many times that their software is allowing
access to my system and they should not require its use. No response on it.
