Norton 2015 may trigger a crash on Windows 8.1 PCs that run encrypted virtual drives (which would include Sookasa's Windows app).
This problem has been reported in a thread on the Symantec support forum, and the error has been acknowledged by Norton.Sookasa is not being blocked due to safety issues. This issue is related to a broader tendency by antivirus programs to block operations they do not recognize and is not a reflection of Sookasa's safety. Sookasa remains the best way to protect your most sensitive data.
We suggest downgrading to Norton 2014 as a temporary workaround until Norton provides a more comprehensive fix. This will provide you with antivirus protections in addition to Sookasa's file encryption solution.
