thank you for the explanation. I will briefly explain my testHi Evjl's Rain,
Both products have the same protection and detection features. Free has a minimum update interval of 2 hours compared to 15 min for Pro. The paid version has also more configuration options, e.g. for the real-time scanner. No technical support over phone and email for the Free version.
There can be different reasons why the testing results varied. It depends from the testing scenario and product version. Example: If the unknown files have been uploaded once, they will not be uploaded again and just compared with the file hash for a decission.
If the configuration was identical I can just guess that this might be related with the missing browser protection in Avira Free that could be used as additional sensor for the upload logic.1/ tested first with avira pro, almost everything was uploaded to the cloud and got blocked
2/ 6-7 hours later, I tested avira free with the same samples (downloaded directly from the main website), fully updated. It uploaded 2 samples and failed to blocked the rest, in other words, heavily infected
