I have tried searching in this forum and different sites regarding the error below but have been unsuccessful. I keep getting this message from 1 machine out of 1300. Error message: 5/27/2011 5:23:14 AM - During execution of Kernel on the computer ********, the following warning occurred: Virus scanner initialization failed. Antivirus protection will not function properly. Computer details: WindowsXP ServicePack3 ESET NOD32 Antivirus 4.2.71 and last virus sig is 6156 I have tried uninstalling ESET(uninstaller in ESET program files) and deleting all ESET folders on the machine. I then reinstalled ESET, rebooted the machine, and logged back into the computer. As soon as I logged into the computer, ESET began displaying that error message again. I then found somewhere online that people have cleared the update cache. I cleard the update cache, ESET was fine for about a week, and now getting the messages again. Let me know if I can provide anymore information. Any suggestions are greatly appreciated?
