As MS Sky Drive only allows files, not folders, for storage, I have to encrypt an entire folder using the PGP .sda system, and previously there were no problems in downloading any folder from Sky Drive and then simply decrypting it.
Hopefully I'm right in saying that PGP is as trustworthy and secure as it gets (I have v8.03), but Insight now quarantines every .sda I try to download telling me very few people use it or that that it had detected WS Reputation.
All very frustrating that I can't download harmless folders that I have created myself using the respected PGP without hassle. I now have to have Insight turned off but the .sda folder is still quarantined if WS Reputation is detected.
