I was on Symantec's website trying to manually update my virus definitions. I had the task manger up, when LuCallbackProxy .exe appeared, the download ceased saying it was completed. I tried to open downloaded file and error message came up saying it was corrupted or incomplete.   Tuesday its worse then any adware!!!!   zak lucallbackproxy.exe is from norton anti virus long version on this name is liveupdatecallbackproxy.exe = no virus or spy it is a part of norton anti virus   noobhunter_ger I accidentally opened my task manager and when I did, I seen alot more tasks running than usual. So I looked throug hte list and found this LuCallbackProxy.exe in the list at least 7 times. When I tried to "end process" on one of them, it told me that access was denied and would not let me end it. So I decided to Google it and see what it was, which is what brought me here. As soon as i clicked on the link to come here, every single one of them suddenly stopped.   Shirley Urbanec last time i scaned for a virus i have found that file runnig like 12 times at the same time after removing the virus it has stoped runing as much as it did before.   SAied Ar its got something to do with Symantec Antivirus do a google search  See also: Link   Damian Redpath ucallbackproxy.exe is a process belonging to Norton/Symantec Internet Security which protects your computer against Internet-bound threats such as spyware and trojans which can be distributed through e-mail or attack directly to the computer allowing unauthorized access to your computer. This process in particular assist with software updates and is important for the stable and secure running of your computer and should not be terminated   when under Windows it is part of trojan   JR 2 no 1 The file is not dangerous. It is a part of various Norton security suites' liveupdate feature. While not dangerous, it is an intensive resource hog, and you should contact Symantec if you're having issues.   Tim M. Ist auf jeden fall irgend ne shit den mein PC ganz schön in die Knie zwingt. Habe ein Dualcore mit 2* 2.2Ghz und 4gb Arbeitsspreicher und solangsam wie der Pc läuft war er noch nie kein plan was das ist aber ich werde auf jeden fall Norton Löschen deinstallieren und mir Kaspersky drauf machen is auf jeden fall besser als Norton und bremst den cp nicht arg so runter das ich um mein Arbeitsplatz zu öffen ca. 2 min brauche und dabei meine Senseo anmachen kann und mir ne schönen cafe ziehen kann..   Porto Talk about slowing my system...Not even sure if Nortons worth it   it eats resources and slows my pc   It matters little if it is Norton or not.... the program eats up huge amounts of computer resources, making it malware at best and a trojan at worse. Norton needs to clean up this resource hog now... or people need to stop buying their products.   usar4me It is part of the Live Update feature in Symantec/Norton utility. Action: Disable Autoprotect in Symantec/Norton Anti-Virus. This fixed the issue for me, and I found my system was signficantly responsive afterwards.   Van Remove it,if it is causing you problems. My computer was almost virtually disabled from it, removed it, and now runs good as gold.   Peter Criss It's a very annoying part of the Symantec Security Suite, it is a resource hog, and happily bogs down most business systems due to their lack of technology upgrades.   KM Just noticed the same behavior as "Shirley Urbanec" above.   JRS I was updating symantec when i noticed the file. Sure takes alot of resources from my computer which i hear symantec is real bad on system resources.   bob If you know more about LuCallbackProxy.exe, share your knowledge and help other users.
