I upgraded my host from Debian Lenny to Debian Squeeze, and now my CMS Made Simple site is spewing PHP errors all over the screen. I thought I'd upgrade the CMS because I haven't done so in a while, but Google Chrome tells me that the CMS Made Simple site is infested with malware.

What are my options now?

Example errors:
