In addition to what Zenosincks says could you also do this,
Go to Start > Run and copy/paste or type: taskmgr
* Under the Processes tab find the following tasks or processes:
ViewpointService.exe
ViewMgr.exe
* Highlight and click "End Process".
* Exit Task Manager.
Click on Start > Run and type: services.msc
* Press "OK".
* Click the "Extended tab".
* Scroll down the list and find the service called "Viewpoint Manager Service"
* When you find the service, double-click on it.
* In the Properties Window > General Tab that opens, click the "Stop" button.
* From the drop-down menu next to "Startup Type", click on "Disabled".
* Now click "Apply", then "OK" and close any open windows.
Click on Start > Settings > Control Panel > Add/Remove Programs > highlight and remove all references to Viewpoint - i.e. Viewpoint, Viewpoint Manager, Viewpoint Media Player.
Finally, delete the following folders if they still exist:
C:\Program Files\ViewManager\ <-- and delete this folder
C:\Program Files\Viewpoint\ <-- and delete this folder
that log is quite badly infected and very bloated.
