[QUOTE="Gandalf_The_Grey, post: 1057155, member: 52096"] Since last Friday I can't open Excel files delivered by mail and saved to my Downloads folder in protected view anymore. I get the error message : "The file can't be openend in the protected view. Windows Defender and Simple Windows Hardening logs show no blocks. But P-Link HomeShield Pro (powered by Avira) shows a blocked domain: augmentation.osi.officeppe.net with reason phishing.

When disabling the web protection of my TP-Link router nothing changes, I still can't open Excel files in protected view. So, it is probably a coincidence, but wanted to mention it, because I'm not sure.
