I've taken my site offline until my server guy checks things out.
Ken Blanton picked up a virus when visiting my build log.
I've run an up to date scan on my PC, and I'm clean.

The virus is a fake alert to download protection software:

My server guy will have a look tonight, and once he gives me the go, I'll turn the site back on and pass on what happened.

sorry for any issues,

Kirk
