Corrupted Link

Every now and again you should check the links that you add to your site. I know that you're not responsible for other site content, but nothing worse than clicking on a link and finding that it gives a problem. Well I just happened to click on a link to a site that we had included, luckily McAfee immediately warned me that the site was running software that was trying to gain access to my PC. The site was science.blogdig.net - now maybe there was no major problem, but I really don't want any issues....
