Same Threat every few minutes

Hello everyone,

since I started my PC this morning this Threat keeps appearing every few minutes:

Threat name: SWF:CVE-2014-0543 [Expl]
Process: C:/Windows/System32/svchost.exe

I have no idea what that is and why it keeps popping up again after a few minutes.
Its the first time I see this Threat, yesterday was just fine.

Can anyone help me please?
