Once I had a too bad experience with Avira System Speedup. My laptop freezed, did not work anymore. I had to call to a Technician for format it. Fortunatellly I did not try on my main computer, a desktop. So I do not trust on Avira System Speedup, and so I will never . download the Avira Prime. I use Avira Pro, and it is great. After that terrible experience, on my laptop I use Avira Free. Always with care, of course. I am not an expert.
