hi members!

i just bought kaspersky 2012, before i install it got some questions,

desktop hardware bought & i install the programs myself but not the originalla... dnt knw what it means, basically my hubby's desktop.
existing crashed, so he just bought the cpu but got his friend to install the internal things but seems that if i wanna browse the net, virus may kena & crash again... so i bought the license to install.

Question - do i need to add on any other programs to support browsing. with the new cpu i havent tried browsing yet cos if crash again my hubby angry since it's his work pc. last time crash, cannot save all his doc's, damn frustla.......

so pls help to advise accordingly. thanks.

thanks for your info!
