So, I spent way too much time trying to figure out what was causing the problem and finally figured out that it's a script in the footer of my template - a script that has always been there, and Avast never cared before. I removed it, and the warning went away - but the template didn't show up properly. I put it back, and the warning came back. I even checked the page where I originally downloaded the template - Wooden Fence template - and got the same warning when I tried to view the preview. So, nothing has changed. Avast just suddenly thinks it's a problem. I got an email from my dad and a facebook note from my brother this morning that it's doing the same thing for them.
I added my page to the exceptions list, so at least I can load it now, but I'm thinking it's about time to find a new template. It's about time anyway, but this just gives me an excuse. I spent some time yesterday looking for a new template I like, and I found a couple. They will, of course, need some tweaking to make me happy, so hopefully I can find some time - between cooking, cleaning, going through the mail and throwing out all the pre-approved reward cards applications, and just generally trying to get this place straightened up.
Re-designing the blog sounds like so much more fun...
