Sorry for your question I forgot to answer.
If you want to play games and your games are detected as dangerous by Smadav and blocked, try temporarily disabling the protection so that your game can run smoothly.
Settings also allow windows scripts and macros to restart, then select exit Smadav.

Hope this step helps.
The latest Smadav is indeed more violent, blocking more applications that are not digitally certified, because of the widespread spread of ransomware which is very detrimental to many people.
If you wish, try attaching here any files that Smadav blocked for me to check the file is safe or not.
Also attach a photo / game name from your game whose exe is blocked by Smadav.
Sorry and thank you.
