SUPERAntiSpyware

SUPERAntiSpyware is anti malware program that I read about on Internet when I got interested in finding out about running software from a USB drive.  I got interested because the hard drive from Blackhawk is now connected to jaywalker as a USB drive since blackhawk broke.  TurboCAD is still installed on the blackhawk hard drive, but it won't run anymore because either it just won't run from a USB drive or because it was installed on an Win XP OS on blackhawk which turboCAD no longer finds when it tries to start on jaywalker which is running win 7.

But SUPERAntiSpyware seems to be a good anti malware program and the benefit compared to others is that you could run it from a USB stick that you connected to an already-infected computer.

Blackhawk broken

Took Blackhawk computer (computer at Cotton Plant) to Uptech Computer yesterday (2012-12-12) because it won't boot at all now.  It started hanging after reboot earlier this week (it has Windows XP) and so I brought a Linux disk and tried to boot into Linux.  After it tried unsuccessfully to boot into PC Linux OS (live CD), it hung and I rebooted again. Now it won't even get to the motherboard splash screen which is always the first screen to appear on reboot.  The Linux disk must have corrupted the CMOS or something.

2012-12-18 Uptech said there was a broken chipset fan on the mobo of blackhawk and that they could not find one to replace it with because it was an old mobo.  I don't know how hard they tried to find an old fan that would replace it.  It was a flat little fan that screwed into the mobo over some chips or chips (I read about chipset fans and they seemed to be mostly for northbridge and southbridge chipsets).  Fan was parallel to mobo when screwed in.

So they offered to put the hard disk into an external enclosure so that it could be attached to any computer as a USB drive.  They only charged me $70 which was about half for the enclosure and half for labor.  So data from blackhawk is now copied onto the jaywalker hard disk and the blackhawk drive is plugged into a USB port on jaywalker.  Blackhawk had not really worked right in a while anyway, because its old Win XP OS was not booting into a standard desktop view and the task manager would not come up.  So blackhawk - the computer built from scratch by David Curran and I is gone!!!

Linux command reminders

ps -e    --- (process status) shows all processes currently running
shutdown -r now --- reboot
pwd --- shows what directory you are currently in.

filenames that begin with a dot (like .memphis) are hidden
ls -la --- this shows hidden files in listing

cat /etc/*-release   --- this shows which version of linux you have
uname -a --- shows which kernel you are running

df  --- shows disk size and available space on disk (disk free)
free --- shows amount of memory installed and amount free

The following commands added 14-March-2013:
su root - to switch to superuser

sudo usermod -a -G wheel margie (This command ads margie to wheel group. The wheel group is the admin group I think)

id username - shows info about user

/bin - many programs

/usr/bin/system-config-users  -- this is graphical program to add/modify users (on LXDE fedora)
