Manually Removing Dell Equallogic Virtual Storage Manager plugin from VMWare

I tried unregistering plugin before removing virtual storage manager and it didn't remove completely. I still use equallogic just don't want to use the virtual storage manager any longer.  I have these two plugins listed in vsphere, is it save to remove both?

extensionList["com.dell.equallogic"] Extension
extensionList["com.dell.EqualLogic Virtual Storage Manager for VMware"] Extension
