can you sync your ipod to your computer w/o erasing the music on the ipod?

[Lakers_allthe_way_47l10]

my computer caught a virus last year, and i have all the music that i had on the laptop before it caught the virus on my ipod. i tried to sync the two together after i got my pc back but it kept saying that it was going to erase the music on the ipod. Is there a way to put all that music back on the computer (Itunes) w/o erasing my ipod?
