I have been stopping or disabling the Office Click To Run service/program whenever it kicks off. Can't always disable it and can't un-install it or won't be able to open office documents. But it takes up cpu and memory when it runs, and uses the network. Basically i don't need an installation program running all the time when i'm not installing something. It does degrade performance quite a bit and causes a lot of disk activity.

I have been getting this error message recently "Microsoft Office OsfInstaller has stopped working"
This is the only place I have found any actual information about this file but I still do not know what action, if any, that I should take. What I already tried was to to restore the pc to an earlier time, before this problem surfaced, and that worked for a few days. But now it is back again. It may be related to a website I visited that gave me a warning about unsecure scripts, and a https warning. Maybe that website downloaded unsecure scripts to my pc? I use AVG free and it did not detect any virus. Hell, I don't know what to do.
