what is npgtpo3dautoplugin?
Safari 6.0.3 has begun hanging. Even Force Quit will not break it loose. After forcing shutdown (power off) Safari is still hung (spinning beach ball). Activity monitor shows Safari plug-in npgtpo3dautoplugin using 215% cpu and 729 MB of virtual memory.
What is this and can it be safely deleted? How best to remove?
Thanks
iMac, OS X Mountain Lion (10.8.3)
