    try ca anti virus, for me its the best, real time scanner is very light, unlike other anti-virus makes your PC stuck at 5-10secs.
    I have a copy, license will expire on 2015,
    you can download it here>> ca-anti-virus dot weebly dot com.

    Jeff why would anyone use a 2003 version? Besides from 2009 Norton re-wrote the entire program.
