Sometimes when I get a link I’m not familiar with I Google it and sometimes I get a result, sometimes not. When a link doesn’t get any hits, what other way can I check it out safely? Yes, I have a virus scanner and other anti malware/spyware programs, but I’d still not rather go to a Website that will try to infect my computer.
There is nothing that is 100% safe, as new threats appear all the time. Aside from using someone else’s computer instead of yours!
I would recommend Firefox with the NoScript add-on. This combination prevents many common problems (usually associated with Internet Explorer - I assume you use Windows) and in addition block malicious (or rather, all) javascript, which is a common vector for attack.
If you are really really paranoid and have not got access to (ab)use someone else’s computer, you could get hold of on of several Linux distributions that run as a stand-alone operating system on a thumb-drive.
Even if this was compromised - which is very, very unlikely - the damage would be limited to that OS, which could be overwritten if you realize there was a problem.
The Offbyone free mini-browser is pretty hard to hurt. As far as I know, it renders html and that’s it. No java, no flash, no activex scripts, nothing. Hard to get an infection that way. It’s becoming increasingly useless as an actual browser though!
You could put the domain name in a whois search and see what pops up. If it is hosted in China, Russia, Bulgaria, or Nigeria, unless you are an exporter to those areas or have relatives there, it’s probably not something you want to mess with.
There is also the Web of Trust. This is basically a voting scheme for internet sites; members flag sites that contain problems (malware, spyware, email grabbers). Then when you get a list of url’s (like from a Google search, etc.) the WOT Add-on marks each url with a stop-light type symbol (green, yellow, or red) to indicate how trustworthy the url is.
This obviously only partially helpful; it depends on others having gone to the same url before, discovered problems, and flagged that url. So newly-created or obscure bad urls may just show up with nothing known about them. And it could be subject to manipulation; there seem to be some church groups trying to flag all atheist or gay sites as ‘untrustworthy’. But at least this gives you some idea of which urls are bad.
You could try sandboxing. Either by running your browser within a sandboxing program such as sandboxie or by using a browser extension that lets you run a tab in sandbox mode. I think Chrome has that option - I’m not sure about IE, FF or Safari.
I like to check suspicious sites with multiple resources, since none of them can keep track of all the bad guys out there.
Another good resource is http://www.unshorten.com/. If you have a shortened URL, like a tinyurl or bit.ly URL, this will show you the original URL. You can then feed that to one of the resources above.
