Some time ago i had made an antivirus scam but my antivirus could not open and scan a file that was strange to me. The path to the file is


"C:\ProgramData\Microsoft\Windows Defender"


The file's weight is 0KB, the file is also hidden. My amtivirus's publisher wrote that if it is 0KB weight that can not be a malicious and I need to ask Microsoft what is this file used for.


The file's name:



"IMpService77BDAF73-B396-481F-9042-AD358843EC24.lock"


I found a similar topic on Microsoft but the person posted it, wrote that he can't use Windows Defender to scan when I can scan my pc using Windows Defender without any errors. I'm interested what is this file used for. Thanks for help and appreciate every answer.


Edit: Now I found that this file is only on my computer when I turn on periodic scanning by Windows Defender. When I switch it on, I can see an "Antimalware Service Executable" process and the file is in the folder. When I switch periodic scan off, the process and a file disappear.
