Thanks for the tip but unfortunatelly, this isn't the case.

I'm still clueless about why this problem occurs :-(.

Some sites report, that Comodo is causing this or the Skype 4 Beta -
which I have both installed. But deactivating (or exiting) both - which
is recommended on those sites to solve those problems in 100% of the
cases - didn't do anything for me.
