see what u using yr comp for ...if just some normal work plain
surfing no difference if u got a up to date comp hardware and
software set up...won't notice a difference. if u into intense work
(video, up/ downlaod files, gaiming etc) then maybe such sfotware
slows down the system a little..worse if u got a near obsolete
system.
if u got no security, personal important or credit card info...i
say dun run any anti virus. let the trojan horses and spyware in.
set a periodic timeline and scan yr system while u are off line and
wipe them out then.
after all i only fear cases that are epidemic...like back in 2003!
