Better and cheaper are better words And cheaper
i was talking about detection rates/footprint..of course if u compare the price of each product along with the support it includes, then avast is much more better..
i use norton many days ago..it is crashed my system every time..also it hang up my pc...so i switch to Avast..it very fast..it is required only 128 MB ram
did u use norton 2010 or 2011 because these versions are very light i think as light as avast(haha i didnt say almost tech ) and at least in my system they ran smoothly..
