It sucks a lot of memory usage out in Windows XP. Shutting it down in the end programs list doesnt work. You have to remove the original file
When this file runs i get many popups ans now and then my system reboots. If I turn it off it seems like all is well. I do not know what is starting it as it is not listed in my msconfig startup box.
It is part of a security software package commonly provided by ISP's.

It is part of the COX security software, but it apparenlty causes memory error messages (two of them) when the computer is shut down, i.e. it must have a bug.
My PC runs pretty crappy with curtains and any other virus software... And yes, it came with Cox software bundle, and sometime takes upto 40% of my CPU for extended times....
Ray Pearcy had it right. It is bundled with Cox Security package for Adware blocking. It is process intensive at times but to dosable it disables the Security Software

i have contacted authentium inc. about this problem.{it is part of cox security soft ware bundle} and was told that nothing would be done to fix this problem on this version but that updating to the new version would cure the problem unfortunately the user interface in the updated program lacks in that it is hard to tell when it is done updating or scanning i am choosing to stay with the older version becauseit is a nonharmful problem
It takes a lot of memory but if I shut it down, my Internet stops working.

Best practices for resolving CurtainsSysSvcNt issues

A clean and tidy computer is the key requirement for avoiding problems with CurtainsSysSvcNt. This means running a scan for malware, cleaning your hard drive using cleanmgr and sfc /scannow, uninstalling programs that you no longer need, checking for Autostart programs (using msconfig) and enabling Windows' Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off repairing of your installation or, for Windows 8 and later versions, executing the DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.

To help you analyze the CurtainsSysSvcNt.exe process on your computer, the following programs have proven to be helpful: Security Task Manager displays all running Windows tasks, including embedded hidden processes, such as keyboard and browser monitoring or Autostart entries. A unique security risk rating indicates the likelihood of the process being potential spyware, malware or a Trojan. Malwarebytes Anti-Malware detects and removes sleeping spyware, adware, Trojans, keyloggers, malware and trackers from your hard drive.
