I recommend searching for Victorious fanfiction on fanfiction.net and sorting by highest rated or most reviewed to find what fans consider the funniest. Humor is subjective, so what one person finds funny may not be the same for another.
Fictionpress.com is the sister site. For other fanfiction sites, I have no idea, I've only ever been to fanfiction.

Yes, it is legal. Fanfiction is subject to intellectual copyright. You cannot officially publish your work, but as long as you are NOT earning money from your stories, it is perfectly legal.
To find any fanfiction you want, go to your search engine and type the word "fanfiction" (or "Fan Fiction") and the title of the movie, TV show, book, or whatever it is you want to find fanfics for! Fanfiction.net is going to have the most fanfiction for any topic.
It is impossible to embed viruses in a story. It is automatically filtered out. The ads may have viruses, and there were a few infected 'Fanfiction is brought to you today by...' ads, but this is somewhat rare and they do give you an ad blocker.
Fanfiction.net has 10 up fanfic as well. Just select K->K+. But some stories might be rated wrong.
No, there is not.

Yes, boys can and do write fanfiction. Fanfiction is not limited by gender and anyone can participate in writing fanfiction regardless of their gender.
No, fanfiction.net is free.
