I installed another (free) AV for the time being.
No BSODs yet!
What I did notice however was the state of the network icon
When using Avast the icon would show as 'Local and Internet' to begin with, but this would change to 'Local only' if I was not actively using the internet.
If I then launched a browser it would connect and then the icon would change to 'Local and Internet' until I went 'inactive' even if I was just reading an article.
Clicking a link would change it back to 'full' etc.
With the temp' antivirus the icon is always at 'Local and Internet'
The BSODs occurred during browsing sessions and maybe, just maybe, that change is linked to a conflict between Avast & my network card drivers (wireless)
There is another post mentioning (no BSOD) something similar with a wireless card.
I cannot take the chance that a new release of Avast might have solved the issue without a positive indentification of some sort and that seems to me to be a chance in a million.
