No i'm not :-) I just want to maximize performance and still keep security. BTW - So according to your saying - I can disable the "File Creation" right? ( Assuming im not sending this file to anyone)

I'm using Eset NOD32 AV program ( version 9 , but it doesn't really matter). In the "Scan" section I have these options : My personal goal is to Still have protection Maximize performance ( without hurting protection) IMO this can be done , I might be wrong and hence I ask : Question Can I set only the "File Execution" option so that only when file is executing , scanning will occur ? I mean : File open : If I disable this , so file will be read by the "File Execution" phase. so why read it when opening while I can read it when executing ? File Creation : If I disable this , fine so a virus can be in that file and if I send that file to a friend , he will be infected , but let's leave this for now. I'm talking about my PC only. If a virus is in that file , so it will be found when executing. Considering the above , Is it OK to leave only the "File execution" flag on? NB It all boils down to the "file Execution" meaning. clicking on txt file , Or an EXE program loading an infected dll , is it "executed" ? I don't think so. The loader read its extension and execute the NOTEPAD process. or is txt file actually executed ? A clarification is needed here. Additional Info , I don't know if it help but clicking the "info" : Asked also here: hxxp://superuser.com/questions/1114031/can-i-rely-on-my-av-by-setting-only-the-file-exeuction-option
