I saved the EXE file into a seperate folder.. now when its deleted i just copy and paste back into the orignal foldet.
I have also added the files to the "permitted lists" in my visus checker.. But they still occasionaly get deleted..
Do you have more than 1 antivirus protectors running on your computer, f.e a 3rd party AV and windows integrated AV (Windows defender)?
A shot in the dark, try 1 thing, in windows go to Settings->System->Storage->Storage Sense Checkbox, see if it is turned on, it should not be deleting files in use but you never know.
Another thing, Windows Button->Find Windows Security->Virus & Threat protection->Manage ransomware protection, see if that is turned on, it should only block file access but who knows! (If on, don't turn off though)
Also check your protection history, see if windows defender is putting the file in quarantine. Windows Button->Find Windows Security->Virus & Threat protection->Scan history.
Only times I have seen executables disappear is when an antivirus program takes it out of commission, I am not having any such problems with Windows Defender though.
