Hi, I have ESET installed on all my clients computers ( 90PCs). Yesterday I pushed to my client's PCs some WSUS windows updates from the WSUS server and the next day more than 30 clients were not able to log on into their PCs through their domain credentials. I went to investigate the problem and I logged into their PCs locally and saw that the updates are still waiting to be installed, however I got the following warning from ESET. WARNING! APPLICATION MODIFICATIONS DETECTED DURING COMMUNICATION A CHANGE WAS DETECTED IN THE APPLICATION:C:\WINDWS\SYSTEM32\WINLOGON.EXE Also another warning with the same wordings accept it is for: APPLICATION:C:\WINDWS\SYSTEM32\svchost.EXE Can somebody help me or recommend changing some ESET settings to prevent any blocking of WSUS windows updates that I will deploy in the near future. Thanks a lot.
