java - Antimalware Service Executable slow down IO operations -
i have java program write temporary files in temp directory. temp directory on ssd. write operation fast. specific sample data very, slow , cpu of antimalware service executable high (30% - 35%). write speed approx. 50 kb/s. if set breakpoint on write loop cpu of antimalware go 0%. if continue cpu of antimalware go high. can repeat multiple time. it antimalware scanning temporary data intensively. why occur , how can prevent this? to prevent scanning can exclude files being scanned file name, directory name, file extension of associated process. so, open “windows security essential” or “windows defender” (type in start menu). go settings -> excluded files , locations.
