I recently installed a bonafide Dragon Dictate 12.5 on my pc running windows 7. My PC is now so slow with mscorsvw.exe and ms installer utilising all of the cpu resource repeatedly. Each time I shut down there are several updates to process. Might seem an odd place to ask for advice but on researching the net for these files I have found that these .exe files could be trojans. Can anyone offer advice to help me out here please. I stop the .exe programmes running using my Norton 360 resources facility but I am concerned that my pc may have been infected somehow.
