People host malware anywhere they can. It's not uncommon for people to hotlink malware to googlecode project files. googleusercontent is exactly what it sounds like, a place for google to host user content. its fairly reasonable that someone (likely many people) is/are using to host malicious software. I'm sure that google is identifying and removing this when it identifies it, but it doesnt mean it isn't there. If you provide a place for people to store bits it will eventually be used to store illegal and/or malicious bits :(
