Hi, I'm David an independent advisor and user just like you. I'll do my best to help you with this.
"SSD Utility" is an app which accompanies/supports Toshiba/OCZ SSD hard drives - there's a newer version of the system available that that mentioned in your message.
If you visit the Toshiba Storage website and download the version which supports your SSD the message should clear: https://ssd.toshiba-memory.com/en-amer/download...
Note: This is a non-Microsoft website. The page appears to be providing accurate, safe information. Watch out for ads on the site that may advertise products frequently classified as a PUP (Potentially Unwanted Products). Thoroughly research any product advertised on the site before you decide to download and install it.
Version: 3.4.3335 is the latest version in the download section. I would suggest downloading and installing that.
Regards,
David
