Marcel, I'd suggest following this guide to troubleshoot definition update issues:

Definition Updates Fail,

I keep getting a "Failed to update definitions" notice. It also happened last week. I was told to uninstall and install again but that does not seem to have worked.

I have a Zoom patch that won't install and now my daily scan is not working (since April12th)!

Back working again but I don't know how it happened.
