Why wont you JUST STAY DEAD?
-Process zombies under sin in the name of ‘safe computing’…
No thanks.

Boot sin and instantly youre met with thrashing hard disk.
HORRIBLE on notebooks.
BAD ENOUGH on desktops.

Most would schedule a virus scan, and indeed on my linux I do so. MONTHLY. Via cron.
More than this is OVERKILL.

Root causes:

	Defender virus scanning all the time
	Indexing service(KDE too, its called baloo)
	Driver installer(background updates)
	-or similar SHIT running

Indexing: service.msc and kill it there STOP. Do NOT LOAD. DO NOT PASS GO. –unless you want readyboost

So, how do we kill defender?

Make a shutdown icon to disable hybrid mode and launch it.(see: howtogeek)

Boot a Linux live cd. ANY LIVE cd. (to rid the sin, insert LIN….) your bios key will vary…
F10? DELete? F2? Mash a F buttton until a colored text comes up.
Choose boot to CD and DISABLE secure boot. You may have to turn this on later.

Boot the cd into X11. Mount the main disk drive.

Drop to a terminal/console:

	sudo mount /dev/sdaX /mnt

-or use the UI/X11 interface. X is the last partition(its a number). That should be what you want.
Push come to shove, fire up GParted. You want the LAST one.
Dont do anything here, just close the app.

Kill Program Files(whatever)/Defender folders.
Flush the trash.

reboot. When the disc spews out, save it for later.
Hit enter if the screen goes dark.

There you go.

You cant launch whats not there…Take that Bill.
As far as I know, nobody at Shaft-U has not figured out a way to auto-restore missing files, but the ‘feature’ supposedly exists.

-This works up to TEN.

With TEN, install AVG or the like and turn off background and auto/realtime scanning. Zonealarm is nice but complains a hellfire storm like defender if ‘live’ scanning is turned off. That is what is swamping your machine.

Every i/o hook getting scanned, well SIN opens over 2000 files sometimes in the course of doing things.

And EACH and EVERY ONE of those has to be scanned?
THIS is why things are slooooow.

Turn it off.
scan monthly.

Dont go there.
Dont click that unknown link.
Install anti-malware or anti-hijack tools to keep your browser pages where they should be(and from re-infecting your machine)

uber careful with using files from uknown people. TRUST the source or scan it first.

I have had no issue since XP days between this and a Linux firewall.
