I've got the same problem, however I've scanned a number of times and am not
infected with adware or any viruses.
I'm using a wireless modem, and when I look at the connection it tells me
it's connected (and has been for ages) and it's running at around 48MBps.
However, the internet is ridiculously slow, with most pages either not
loading or taking at least 5 refreshes to load. (It's taken me over half an
hour to get to this support page - aaarrrggh!)
I'm guessing the speed I'm being given is simply the speed of the wireless
connection, rather than the internet connection (cable connection), but I'm
not sure what is causing it. Is this a problem with my ISP, or my PC, or the
user (quite likely).
Help?
