Uninstall TurboTax and C-Dilla
http://www.geocities.com/SiliconValley/Network/8814/cdillaremoval.html
I just finished following a thead at another community, and the guy had C-dialla insinuated on his machine. He had massive trouble getting rid of it, it keeps trying to return and reinstall, and throws up errors at startup.
Anyway, it would appear from all that's happened, that the infestation is linked to the free Preventon firewall, as this is no longer starting with Windows, instead it says a C-dilla component is missing.
