How to detect virus on my blog, put up by my Mac, and appearing on PC of my readers. I have a blog I have posted for 8 years...Lately, I get notes from readers using PCs that they get virus warning. Mac does not detect or seem troubled by these things but can and does seem to pass them on with no problem for my Mac but causing readers to be stopped from my site by their virus detectors.

Any fix for this problem?
