Cant start in safe mode, cant install ActiveX control

hi
I read the tutorial and I am alredy good at since I fixed many many computers...
However this particular one wont start in safe mode
the following message is suplied:
A problem is preventing your computer from being tested for valid registration.
The it logs off and I cannot log back in, but within 15 seconds it just restarts.
So I said ok let me run anti viruses
I run trendmicro and get 24 infections all are JAVA and SUB7 trojans, cannot be fixed cleaned or remover, norton keeps quaranteeing these things but they just keep coming back
Then when I go to the Norton online scan, The following message occours:
Your security settings do not allow websites to use ActiveX controls....
NOW I did go into my security settings and I made sure that ActiveX control is enabled in all possible options
Reinstall winodws?
Or run the removal tools without the virus scans?
If it hellps any the it is the about:blank thing thats causing the problems.

 

Never mind I think I'm about to fix it
thanks....

 

ok its back....
I did everything in the tutorial appart from the safe mode since I cannot boot in safe mode
At home I have Norton Prof. anti virus.
What to do now?
