Not much. But my virus program (norton internet security 2010) told me it's i virus. I deleted it. But im not sure if it really is that dangerous for you computer
All I know that it takes abundant amount of memory to run it and it is slowing down my users PC's.
This is simple the MSN toolbar. A resource hog

Apparently it is Microsoft's "Bing Bar". Runs From: C:\Program Files\MSN Toolbar\Platform\ version here \mswinext.exe. It consumes an abnormally large amount of memory, even when a browser is not in use. You can remove it from control panel- Add/Remove Programs: "Bing bar" or "MSN Toolbar". Avira Antivirus does not detect any virus' when its run/scaned.

It's from MSN toolbar. I don't need it though.
delete the bing bar in programmes and that does the trick

Mine runs in the MSN toolbar directory

mswinext.exe is part of the MSN Toolbar. If mswinext.exe is giving you any problems, it is not harmful other than being a big resource hog. Go to your Control Panel, delete the MSN toolbar using Add/Remove Programs and mswinext.exe will leave with it.
mswinext.exe uses internet resources without your knowledge or control. It slows your computer down by 100 % using virtual memory and causing several Virtual Memory alert warnings. My computer virtually went into a complete stand still. I have now removed it from my PC and removed MS Win Toolbar to ensure my PC runs fast and efficiently. I have a ‘NEW’ PC since removing it! Definitely one of Bill Gates’ worst programs developed.
uses some CPU - Sysinternals autoruns,exe told me that this is started as part of Bing Bar - cannot remember I opted to install Bing Bar - deactivated Bing Bar in autoruns
Listen to Ian Mason; I followed his direction and it did do the trick!

if you would prefer to keep the bing toolbar, you might choose to disable msiwinext.exe in task manager or manage add-ons. Erasing it completely may effect Internet explorer from accessing other programs. I would think it's main purpose is to gather personal information re browsing habits.
It is yet another Windoze resource hog. Use the Task Manager to end this process each session to speed up your CPU when necessary.
