Hi! I have previously had problems with AntiVirus (Norton once) being disabled by a virus which made it hard to start it going again. There are a lot of viruses do not show up on Norton,. You should install a spyware catcher such as Spyware Doctor. I have Stopzilla, (anti-spyware) and cannot yet comment about its helpfulness. They are not free but cost a lot less than Norton. A lot of people prefer AVG Grisoft Free as their Antivirus prpgram but we all need an anti spyware program !Because I get mainly spywares, and rarely viruses, I feel that Norton may be getting obsolete and not providing sufficient protection. I call them all, loosely speaking viruses
Your computer has crashed due to what i will call loosely a virus, it could be spyware trojan etc.
CLOSING PROGRAMS IN TASK MANAGER
What I'd do first it to go back to your task manager, and try to end the
processes and programs that you see running.
Can you see on topbar of task manager, there is a choice "programs" and one "processes".
See the running programs and processes, do you recognize any names there?
The virus may be one of the processes running there. Dont end them unless you know
what you are doing
End the programs you see running there. Try to do so slowly.one by one.
Things should get better once you have closed a lot of programs.
Its a very slow process and you need patience
If that does not work, you will need to restore to older settings and your
files and docs stored on hard drive will not get lost
SOFT RESET/SYSTEM RESTORE
You need to do a system restore.
How you do that depends on what make you have such as Dell, advent etc
Maybe you'll need to switch on, and while it is booting, press F12 or F10.
You will to check with the manufacturer how to do system restore. You can
find instruction manuals online etc.
Here your computer goes back to the way it was at a restore point created on a
previous restore date.
HARD RESET/RESTORE TO FACTORY SETTINGS
you probably wont need to do that. Your stored files and programs you have installed
will get wiped out.Unless they are super-important, let them go
Get back to me if you have more difficulties and i hope u found that to be of somehelp
