MS ASN1 Integer Overflow TCP 1

[Nazgulero]

Hello,

I am being ´attacked´ about 40 times a day, and Norton Antivirus 2006 tells me that this happens because of ´MS ASN1 Integer Overflow TCP´. The problem is that every time this happens, my Internet access gets blocked for about 30 minutes. Is there anywhere I can change this value, that is, to have Norton detect the virus but NOT block my access ?
Thanks a bunch in advance for your help !
