Thanks for your response. I hadn't realised my version was that old; my application settings were set to auto-update. Attempting to install the latest version failed as my system fell foul of 2019 SHA-2 Code Signing Support requirement for Windows and WSUS However I was able to successfully install the Malwarebytes version 4.3.0.xx for Windows legacy build and this doesn't report PhotoStudio.exe Windows 2019-09 Security Update for Windows devices running Malwarebytes home products This dinosaur has defective eyesight and is restricted to very limited hours on the computer, including that for debugging. Your reply lead me to the solution relatively quickly which is very much appreciated. Thanking you.

Ignore this particular comment, I've found a way around this and added the program to the list of exclusions.

BTW When I go to MalwareBytes > Quarantine, this program is not listed. How do I restore it from Quarantine if it is not listed?

PhotoStudio.exe falsely reported as ransomware. 'been running same program for 10 years so I kno' it ain't ransomware. Log20240311.txt
