As do I per your recommendations.
Still during a google search I hit a site which breached security.
I was looking for source for a shareware game to test my
reflexes after a recent incident and up came a site
promoting Warez :-(
Repeated attempts to close the browser failed as it kept reopening :-(
I killed the dialer to eliminate that threat then deleted
Win temp files.

No idea how this clown's code breached my system.

 Well the heater only takes 14 watts.
 What the heck I conserve power.
 I do have the monitor powered down in Win 98 but the
 system sleep mode is invoked in CMOS.
 Don't ask me why but any other combinations cause lockups
 and problems.

Yeah but why was the C drive not recognized in any way except through
booting Linux and mounting it there where all looked well?
It is a puzzlement.

 The computer is by design on a completely separate leg
 of my wiring and has a surge protector.
 AC, refridgerator and microwave are on different circuits.
 Load on this leg is at at MOST 400 watts with no inductive components.
