I have a forum/groups site that contains a lot of external URLs, sometimes direct download links. I want to protect my visitors from possible attacks from malware sites as they are mot likely to click on these links. CUrrently I implement DBL (spamhaus) but thats not enough. I want to run a background task to check the outgoing links first. I have looked at similar questions in StackOverflow (wrongly posted there) and here but fail to find a question same as mine or a good answer.

People have suggested ClamAV , I don't believe it can detect Web hosted malware sites and its has a lot of missed detection. I have looked at google safe browsing service ( http://code.google.com/apis/safebrowsing/developers_guide_v2.html very complicated to implement or maintain plus midway I get lost :S )

I can go for commercial solution, anything to protect the visitors and my site brand. But I would like to hear the opinion of server admins and if anyone has implemented such a service.

My Server is basic CentOS LAMP stack.

thank you very much in advance.
