A client has this problem where it is now saying wrong digital signature for add-on when starting up any add-on. Some of these add-ons have been running for months/years.
It even does it for the XL Reporter add-on and the Fixed assets as well as the add-on I developed for them.
Seems like they had a virus, ran a virus scan without removing or deleting any files and now this.
Any ideas on how to fix it? Any advice welcome and greatly appreciated.
