You would be surprised at what some people will work with when they don't know any better. I have had many people bring me their computers to fix that are riden with about 400 virus/trojans and about 800 pieces of spyware/malware. Machine runs at about 1/5 the speed it should. Web pages take at least 2 minutes to load. Yet they kept using it and only brought it in because the infection prevented them from doing something they want to do or causes their machine to reboot too often or something like that. As long as they can keep using their machine for what they want (surft the web, check email) they keep on using it and just deal with the issues. Because they are not concerned with speed as much as we are. Thus they just don't care. Could have very well been the same here. Maybe it was running a lot slower, pages taking forever to load due to the stuff being downloading in the background... but maybe since he didn't really know any better he didn't see that as being a problem. For some their machine may get slower over a few days or weeks and they just don't realize much till the end that what use to take 20 seconds now takes a minute.
