This problem seems to have started in the last couple of days. Basically, any external links I add to my Facebook profile to only one of my websites get blocked by a security message. I've done a check and there doesn't appear to be any viruses or malware present. Also, if I install site advisor, when I go to my website is also reflects the website as being dangerous. Can someone please shed some light on what is going on.
This is the website in question
Yes, I see it.
You're rated Red in SiteAdvisor. One negative review dating from 2009 : how long has your site been up and running?
In the TrustedSource information the problem is with "Web Reputation", a category which covers a multitude of sins. Could be absolutely anything, from a previous user of your IP address with a bad history, to a problem with your hosting provider, to a malware-detecting service somewhere flagging your site for some obscure reason. WhoIs says you've had 5 IP addresses in 5 years, so that might be relevant.
You'll need to take this up with SiteAdvisor and/or TrustedSource. For TrustedSource,
