I just had to remove a link in my list of language learning blogs to a site that is apparently infected with malware. It was called speakingadventure-dot-com (it's spelled out...DON'T GO THERE!!!). I did not click on the link at any time after that site was compromised so I doubt I was infected. The link had been on there for quite some time but the site must have recently gotten infected as Google Chrome would no longer let me on my blog site and gave a malware warning about content from this other site.
Though I could not get to my blog at all, I could get to the maintenance pages, and I just searched all the gadgets for any trace of the site that Chrome was telling me harbored the infection. And, bingo, I found a link to it and just deleted it, resolving the problem in less than ten minutes after getting the warning and being blocked from my site.
So keep in mind that at any moment, any link that you have posted on your site could become infected somehow. Or, even worse, someone could hack into your site and it could become infected as well. Sobering thought.
Whew...I'm glad it was not something more involved, and I'm glad I figured it out quickly.
