Hi, windows xp, Vista a old windows 7 without the update mentioned above will be affected.
This particular file is a tool that makes network operations inside home network scan faster (roughly 10 times faster). When not used everything works correctly, just a little slower (and on small networks you might not even notice the slowdown)
No action is needed on your side, just click the dialog to make it go away, we are releasing re-signed versions today with the vps update.
Thanks. Lukas
