This is what I got back from my my hosting service techs:
"The problem is, you can clean and secure the account as much as possible
but if there are backdoors / injections we cannot find then the problem
will always persist. This is a CMS we are not to familiar with where as
if it was WordPress I could clean it and ensure its safe going forward.
For this account, I would recommend going with sucuri as they know ALL
cms so they would be able to clean it successfully."
I don't think this has anything to do with the Google Minifier issue. Also, I don't know anything about backdoor and injection malware. Please recommend a hosting provider that understands I-U.
