i do not accept using ccleaner as it got items of issues (macafee owned) that i dont want the hassle off. and normal windows with the internal AV have not blocked any files in any informations i seen in the security log.
nor turning off the AV just because of trainer issues.
cleaning the register is ok but even after removing the files in the registery via a registery cleaner and going manualy thru the registery after, and rebooted the pc and i still got the same issue.
Avast owns Piriform, not McAfee (Link). And you only need to create scan exclusions in Windows Defender for the trainer exe file or the folder you store all our trainers in and the Work folder. This Work folder is located here -> C:\Users\YourWindowsUserName\Cheathappens\
