Soap2dayhd.com is ok. Streamed movies are streamed movies. There is almost nothing wrong that can happen to you except malicious links and redirects, unencrypted registration forms and code injection into the browser. Only the last thing is a real risk, but not big. Malware that can be injected into the PC just through the web browser is rare. If you are really that scared, just watch films from this site in VM.
None of the suggested sites have as complete library as the old SOAP site. As an example check "The Last Drive-in". Soap had them all but these have only the first three seasons. I'm sure many others are missing as well.
I don't know much about soap but I've been using dopebox.to for a while just to watch things for a year and it worked great since 2 days ago. Now it's a bit slow but I hope they can handle it somehow.
