S4n1mani 0 Posted December 9, 2020 Share Posted December 9, 2020 Hello, Today I had made an antivirus scan but ESET could not open and scan a strange file that's hidden in a path: "C:\ProgramData\Microsoft\Windows Defender". The file's name is IMpService77BDAF73-B396-481F-9042-AD358843EC24.lock I don't know it is safe file or I should try to remove it. I'm scared a lot, thanks for your help.

Administrators Solution Marcos 5,069 Posted December 9, 2020 Administrators Solution Share Posted December 9, 2020 According to the info I've found, the file is typically 0 bytes in size so it cannot be malicious. Its name and location suggests that it might have something to do with Defender so it's rather a question for MS what is the purpose of the file.

S4n1mani 0 Posted December 10, 2020 Author Share Posted December 10, 2020 Hello again, Today I noticed that this file is being created when I turn periodic scanning by Windows Defender, because create time is exactly the same like time I changed that option in my Windows Defender's settings. When I turn it off, the file is being deleted, I'm almost sure that file helps to make periodic scanning or something like that. Link to comment Share on other sites More sharing options...
