Ok, my download rate goes down to 3500 sometimes now. When I use CCleaner, the download rate is back to around 4600.

Is that normal?

No it is not normal. You probably has some running software with built-in spyware that is leeching part of your bandwidth and its registry entry is being removed by CCleaner, but which is reinstated when the software runs.

Try scanning with a-Squared Free:

The program worked and my internet is back to normal now.

But, it also found tracking cookies. Usually, my AVG Anti-Spyware,Ad-Aware, or Spybot would catch these cookies. All of these scanners don't seem to be finding any infections anymore even after I update them.

When I got the a-squared that you suggested, it found a lot of infections. My AVG Anti-Spyware also found a lot of infections when I first installed it, yet now it doesn't find anything. Why can't my old programs find anything infected anymore? I'm just curious why the programs are like this.

I do not have an answer for you except that it is better to scan with several anti-spyware programs as some will miss certain types of spywares and others may detect them. Now the latest type of spyware are rootkits which are getting harder to detect.
