I have a similar problem and I think it is just avast.
It says my website through tripod is infected with a {gzip} virus.
I omitted what I had on the website last, no change.
I just think avast is mixed up.
Nothing bad was put on that website and I use it to go to other places, have my uls stored there.
So why this bother over {gzip} and gzip is not a virus anyway?

Maybe what I need to do is uninstall avast if it keeps giving false warnings.
