hi,
Are you still on 7.6?????????????????????
I remeber 7.6 was launched in 2000-2001. I think they are installed wither on Windows 95 or Windows98.
Please try to get NONAV 2.611 from Symantec Technical support team and remove it.
If it fails to get remove, then better to remove it manually or else FORMAT.
Its NeW Generation going BOSS !!! pls upgrade to either SAV 10.1.8.8000 or SEP 11.0MR4MP1a.
Rgrds,
SAM
