My suggestion use a different AV software.
What's your Windows OS edition & version and which security software do you use?
Clear McAfee's quarantine and scan logs and create a scan exclusion for the trainer exe file itself.
Normally, you would also need a folder exclusion for the Work folder located here -> C:\Users\YourWindowsUserName\Cheathappens\
BUT: McAfee has no option to exclude a whole folder. What you very likely will find in the aforementioned location is a work file. Delete this file.
You might need to do this every time you use a trainer marked as 'Trainer Manager Compatible' ... or you switch to a different security software (except Webroot).
