ScanURL is a nifty new website that describes itself as follows:

Enter a URL/link (web address) or website/domain below, and we’ll see if it’s been reported for phishing, hosting malware/viruses, or poor reputation. We check with reputable 3rd-party services, such as Google Safe Browsing Diagnostic, PhishTank, and Web of Trust (WOT), who scan websites (and/or collect user ratings) checking for malware, viruses, phishing, scammy behavior, and icky stuff like that.

It’s a bit slow—no surprise, since it’s using several different websites to gather data—but it works very well. Recommended.
