Will this 'high-speed' be enough to Update definitionis ...

Hello - need reply ASAP (sorry)

 

   I  will be installing NIS 2009....will be getting my cable company's 'high speed'' (Road Runner) (not DSL)

 -But  it will be  the entry-level  'lite' version with a speed of 768 Kbps...(I going from 'dial up').... It would cost me 'more' monthly to go above that speed ..

    Will that speed (768 Kbps)  handle the updating of definitions after in complete the installation of NIS 2009 .... thanks so much !
