This page seems to be
http://www.UnmaskParasites.com/security-report/?page=www.packageupdate.cz.cc

Maybe it’s already gone…??

Domain does not exist or is unaccessible.

That site is still there and is malicious.
But let’s help Michaela first with getting Windows to boot.
Without booting there is not much that can be done to remove the infection(s).
