Unfortunately, a complete letdown !!!

Had on my Acer laptop pre-installed McAfee Internet Security 2 years, has worked well until they regularly produced an error for an automatic update. Since eh decency and a new subscription should cost this update directly from McAfee proud 75, I decided to show the current version to buy for 16.99.
Unfortunately it was not possible without errors 7 to install the software on Windows despite Consult the McAfee support and get up and running.
So wrote Coal in the wind and changed to G Data Internet Security. Installation without any problems and the best, the G Data uses only a fraction of the Hpeicherressourcen compared to McAfee.
