If you receive blog notification emails every time someone posts, the email provides a “Comment” button. While the button should take you directly to the relevant blog post to comment, I have received reports that, in some instances, malware already present in your local browser can hijack the button and direct you to the malware ad site instead. The malware does not come from the blog; it appears to come from the browser that you use. Unfortunately, there’s nothing I can do from my end (other to make sure that there is no malware on the site) — however, if you want to comment on a post, go directly to the blog and comment there.
If you encounter this issue with malware, please let me know.
