Well, it really depends on your firewall and antivirus setup.  To be safer, try using a biometric USB drive.  It's not constantly connected to the internet and much safer than scribbling it down on paper as well.  Just be sure to ONLY use the drive for passwords - keep your personal or work stick drives separate!   Not a bad idea to keep the biometric USB under lock and key as well (just because you're paranoid doesn't mean there's no one after you :).
