Why are all my internet connections (DSL, Wireless, Modem) so slow?

I know that my laptop is full to the brim with spyware and adware. I have tried several anti-virus, anti-spyware and anti-adware programs, but none seem to work. I also tried to free up some memory. If anyone has had ths same problem before, please help.

All the answers so far are good.

Also, defrag and run Disk Cleanup
Have you run a registry-fixing program yet? Even if you got rid of the crapware they could have left lots of little things in your registry, which slows the computer right down.
Sounds like you'll need more RAM too!
Just go to the control pannel, click add or remove programs, and get rid of the junk you don't need anymore or never use.
