firefox is great and IE should bite the dust. download it
here.
i dont experience the same problems as you at all. is your internet connection directly into your computer ?
get spybot search and destroy. when its downloaded and installed, change the shortcut on the desktop to read this as the target.
"C:\Program Files\Spybot - Search & Destroy\SpybotSD.exe" /AUTOCHECK /AUTOFIX /AUTOCLOSE /autoupdate /autoimmunize
copy/paste the whole line.
running that at least weekly will keep your spyware/adware at a minimum.
Also use Ad-Aware SE Personal. Update and run it weekly. I tell this same information to lots and lots of people all the time. dont work in computers - annoying things like spyware make the job that little more ####ed.
as for the difficulty connecting to datsun1200.com, try opening a DOS prompt and typing
ping datsun1200.com
or
ping datsun1200.com -t
(to ping non stop)
this'll tell you if your computer can reach datsun1200.com, then you can see if its the browsers fault.
