Avast older version... Can I get adequate protection

Can I install an older version Avast, 4.8 on my dialup computer and get adequate antivirus protection? Can I still get up to date antivirus definitions with an older version? I dont have access to anyone’s hi speed connection. Once I load 4.8 I could possibly upgrade to 5.0. Just need that question answered. Thank you
