Is there a way to test malicious script?

I made a virus a while back, but i never got to test it. Is there a way to safely test it without hurting my PC?

If you know EXACTLY what it'll do, then you shouldn't have to worry, since you'll be able to reverse it all.

You should know that, since you coded it.

Add some status log who send you some information about how it goes and then you could infect someone with it, or you could try to make a verision of it that you can disable when you have tried it enough.

OK i did a little research and found out about sandboxes. Will these be sufficient?
