It seems to probably a malicious software!.
   

Seems from common problems and relations it is to do wirth games. Though the thing is if it is someone needs to send the damn company an email as the file is not directed to anyone, is named like malware and looking at contents it looks unfriendly but the thing is if u are locking up or unable to click run some anti-viruses, clean up ur startup processes and clean up ur comp in general as it is probably lag.

When I open W Live Messengger and I type my account name it takes like 10 sec to make echo (show the caracters I have written) and my router traffic lights blink as I write, so, it's spyware to me. Some coincidences with other posts: My computer is noticeable slower. I have recently installed Call of Duty,

Tried starting up pro evolution soccer 5, never had this problem before and i get a lovely little pop-up box from Windows Defender telling me i need to delete it. Obviously it just appeared again straight away, I'm worried if this is a virus it could be doing stuff elsewhere, anyone know if i can just ignore this or if there's a way to stop Defender recognising it as something dangerous?

Windows Defender kept identifying this file as a trojan when I would run the game Scrabble. I finally decided it was not harmful and uninstalled Defender. Just to be on the safeside though I ran regsvr32 /u cmdlineext03.dll then changed the name of the file to .txt

i dont play games on my pc and with this file in my temp file my taskbar s (by the clock) wont run so my anti-virus is disabled. nothing finds this file.. adaware, spysweeper, norton e.t.c. A search for it in c:\ *.DLL does not show it. however I booted in SAFE MODE and then deleted it. booted normaly and all my icons came back. Also now my pc is using 18% resources as before it was using 50-80% !! I work on computers day in / day out and this is no harmless file.! you have been warned.

I first spotted CmdLineExt03.dll - alerted by 'Windows Defender' to a dangerous Trojan. I noticed it after installed S.W.A.T 4 and launched it. Was able to delete it. Seems it harmelss enough, and from reading above, comes with most games. (retail version of game)

It is harmless. Wrote to SecuRom support to investigate it. The replied: "Thank you for your email. Don't worry this is a harmless SecuROM related file. It reinstalls itself after you start a SecuROM protected game." So just tell your spyware to ignore it. :)

Copy protection, included with some games. Annoying if you want to mount an image as a virtual drive, but not dangerous

Found it in my System32 folder and says it was created 2 days ago, which is when I was download-frenzy on GarageGames.com, may be from their games? Still testing at this point but I do know that 20 minutes ago before I renamed it, my firewall kept restarting itself...

Windows Defender is now detecting this file as malware. Just because it's from Sony, or SecuROM doesn't make it safe. It's a root kit ppl. Even if it's from "the man" it's still potentially dangerous. Especially if virus authors decide to exploit it, and even Microsoft agrees with me. Go figure.

Installed Diablo II under XP Pro last night. I found that after running the game, my wallpaper would change to a play symbol. Further investigation found *something* tried to hijack my desktop using Active Content. I ran Windows Defender and found this .dll. I unregistered it, renamed a txt file with the same name, and copied it to my system32 folder. Now Defender doesn't detect it, it doesn't get reinstalled and my wallpaper doesn't change. Harmless. If it were, Windows Defender would not have alert me to it's presence in the first place.

comes with games protected by Securom copy protection. Harmless

For me when i start Rollercoaster Tycoon 3 (with soaked and wild) it just appears and is quickly detected by Windows Defender Real-Time protection as a high risk file. Not sure if it is actually dangerous (Deleting "CmdLineExt.dll as well as bleaching your temp files are pointless). It's been bugging me for 2 hours and I am gonna ignore it now unless quarintining it works :P
