For what it is worth.
I run McAfee Security with built-in Firewall, Virus Control, etc etc
and also Lavasoft Ad-aware for Spyware control on a Dell Latitud
Laptop. I had a regular update of Ad-aware a few days ago, and shortl
afterwards the PC slowed right down - painfully slow - and everythin
was taking ages. CTL ALT Delete didn't work and it took almost an hou
to get the system monitoring tools up to look at CPU usage etc. Trie
to shutdown and restart but got the dreaded "Logon process has failed t
create the security options dialog ..." pop-up window on a black scree
during the restart. Proceeded on but PC still very slow
I suspected a clash of Ad-aware and McAfee so I uninstalled McAfee an
then re-installed it from scratch in case ad-aware had screwed some o
the McAfee DLLs, but to no effect
Restarted again but to no effect
Finally decided to uninstall ad-aware and rely on McAfee for spywar
control - as soon as I did this and restarted, the PC returned to norma
operations and speed

I don't know if I can help, as I'm not any sort of techie at th
operating system level
My problem - as you can see from my post - was cured by removing th
Ad-aware program. I'm assuming it was caused by a clash of spywar
check programs with/without the operating system, since removing on
caused the problem to disappear.
If you look at the thread of others with the same problem, they seem t
have it from two firewalls clashing, or two virus checking programs etc
Maybe your child started a second virus check program or firewal
program

I started having the same issues. My Dell desktop is two years old by now.

I restarted my computer in safe mode and it worked fine, so I was convinced that it was a software problem rather than a hardware issue.

Then I remembered I recently installed AVG antivirus but failed to remove an old version of Viruscan first.

Long story short after too many hard stops and frustration, I restarted my computer in safe mode, disabled Viruscan, restarted normally and uninstalled it. Seems to be working fine now.

So I would recommend physically unplugging from your network to avoid infections, getting into safe mode, disabling all your virus protection and firewalls, then reboot and see how it works. If its fine, then start enabling your protection software one by one and see which one is getting your computer hung and uninstall. When everything is back in place, restore your network connection and let us know if it worked =)

Hope this helps -
