I'm an Avast! user who gets the virus alerts about every other week or so. I can get rid of them by uploading clean versions of my index.html files to my main directory and subdomain directories, but viruses always return in a week or so. I'm starting to get hate mail from visitors who say they're being bombarded by virus attacks when they arrive at my site. Never had problems like this before, had a paid Angelfire account for years.
Reason I'm posting this here is that I submitted a ticket a while back and got a reply about a week later suggesting the problem was in my computer. In my computer! So I'm getting basic customer no-service there. I've had about as much as I can handle.
