I am Raja and I recently downloaded this software and used successfully up to now. But recently I wanted to update this software but my Kaspersky Antivirus did not recommend it. Now My Lockbox doesn't work and I can't open it.
Use the Kaspersky to add the application to Exclusions list. From what I see, My Lockbox is not a spyware application. This means that Kaspersky wrongly detected it and this is all a false alarm. Just add the application to the Exclusion list and it will work normally.
