I would say search for some company that offers VDSL.. It has same upload and download speeds.. Otherwise cable and dsl providers generally offer low upload speed, as compared to the package's download speeds.
I think when you go into different mirrors from the download test, some of the mirrors include larger test files.. You have to switch to that mirror first though.. Download Test -> Test Mirrors -> Choose one that has a big test file
Those speeds are far better now.. Now your upload speed is what your download speed was before.. Cablenut modifies Windows registry to make Windows accept faster connections in simple terms.. It configures your registry with the optimal settings for your connection type.. Someone got the link to VanBuren's cablenut tweak files?
My Hotmail works fine.. I had that problem once with Gmail when I tried signing in from a school computer.. I'm guessing that its the computer's fault.. Have you tried signing in from another computer?
Hijackthis is used on all spyware help forums that I know of to simplify the process of determining what is causing the problem.. It has been around for a long time and from my own usage, it works perfect!
Try going into Network Security -> WiFi Detection and then click on Connected Computers.. Lets see if it recognizes any computers as connected to your network
Do you have a router installed? Maybe Trend Micro blocks the attempts of the router or hub to connect to your pc and therefore enable that pc to connect to the internet..
