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.
