hey, i am new to this site, i don't even know if this is the right place to ask this on here. My computer has been running slow especially when shutting down, it takes forever to shut down. When it is started up a box pops up saying "error loading C:\Windows\system32\zogovaro.dll. The specified module could not be found." Is this why it's moving slowly and what can I do to fix this? Thank you so much in advance. Your help is really appreciated.
