dongle for steinberg cubase sx3, software application
its a dongle for the Halion Software Sampler
Cledx.exe is part of the syncrosoft protection system. The "Team H20 Cledx" is a warez patch. The real cledx.exe is required for applications using the syncrosoft licensing system.

It is a file provided by Team H2O (Warez). It gives you full access to Cubase and to the other Steinberg products.

The cledx.exe from H2O contains a trojan called Win32:Rbot-cxl

it can make some problems with NOD32
its a dongle safe to use
Dongle Emulator
It is harmless.
I removed it from my Vista system, don't know where it came from, but it's gone and everything still works, still slow as ever.
It's a wonderful dongle emulator for those of us who hate usb keys .. used for alot of different steinberg products-- sometimes produces CLED error but reboot will fix it
Dongle Emulation for Cubase
Emulator for syncrosoft products, including Cubase, Halion, Hypersonic and many more - basically audio programs.
key for Nuendo. May have trojans inside, scan with ad-aware just to be sure. Mine was always clean
Team H20 dongle emulator
its a 'dongle' for people that have a hack/fake version of steinberb music products. you need it to do the music software.
It's not compatible with windows 7 64 bit
its a proccess made by H2O to simulate a fake usb device, when it working, youd be able to load certain plugins and other music making softwares.

cubase dongle, absolutely fine. obviously virus can be attached to any file, so check that your source is reliable. Great job for me though!
It workin only under XP windows, on other(Vista or 7) has included fatal error, witch slows all processes on your computer after starting windows. But, when you have version with "Team H2O cledx" sign in taskbar, its a virus included in programs "SyncroSoft Emu" or "discoDSP Discovery VSTi". Uninstall it!!!. Actually this warez patch is not danger, but your Cubase has instant acces on internet like flash or ftp. Be carefull and protect your privacy.
The console will be initially released in either Black or Blue and some of the games that will be released for the launch of the console include Mario Kart 3DS, PES 2011 3DS, Ridge Racer 3D and The Sims 3. Further, to spice things up, Nintendo is also re-releasing vintage. The virtual communication (street pass) will add to the excitement of users because they won't know what they'll see when they get home.

Best practices for resolving cledx issues

A clean and tidy computer is the key requirement for avoiding problems with cledx. This means running a scan for malware, cleaning your hard drive using 1cleanmgr and 2sfc /scannow, 3uninstalling programs that you no longer need, checking for Autostart programs (using 4msconfig) and enabling Windows' 5Automatic Update.

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 6resmon command to identify the processes that are causing your problem.
