Hi and welcome Traurig73.
There is no virus in LiberKey and all softwares which can be detected as false positive are removed from compilations (but always available in
All applications page).
We have so few informations in order to link LiberKey update and your virus detection : What is your antivirus and what is the virus name ?
Have you make a full scan of your computer ?
And last but not least have you a firewall ?
