Capturing Thumbnail Website Without Security Concerns

I was looking for a way to go to the website URL and take a snapshot of how the homepage looks. I found a solution for designing the code using a web browser control, but people said that it wasn’t for production, and there were security risks (malicious things on the web page, etc.).

Is there a “safe” way to do this without worrying about downloading a virus, etc.? It would be nice to capture the page as it actually is, but maybe the only way to do this is to disable javascript, etc., Maybe? I am using asp.net c #.
