Encryption Key

Encryption Key Change
im using opencart 2.0.3.1 and i just changed the folder it is hosted in not the domain itself.
and kaspersky antivirus is telling me the site is not trusted and something wrong with the Encryption Key.
do i need to change they in admin/settings or is this more serious and why/how
what do i do.....oh nO....what do i do

Perhaps a screenshot of the message from Kaspersky would be helpful.

Alternatively, try checking if it is a SSL issue.
