I have run AVG & MalwareBytes multiple times and they find nothing.
CPU is only running at between 1% & 50% when I look. And I have only used about half of my memory.
Not sure what the problem could be...

Please explain your problem in detail. Also, if the cpu is pegging at 50% that's high. Which process is using the cycles?

The problem in detail is just lag. My mouse will randomly lag. Scrolling on websites or in itunes lags. When I am watching videos online they constantly lag.
Programs take longer than they should to open.

Another problem I have is that after using Firefox for a while it gives me a warning telling me that it is using too much memory. The lag only gets worse after this happens. But even with restarting Firefox I will get the same problem within minutes.
For instance, right now in Windows Task Manager it shows that Firefox is using 250,324K.

Firefox can use that much ram and more.

As for the rest, please boot to safe mode and let us know how things run there. If they seem normal, try a selective startup:

Open msconfig and on the General tab choose "selective startup" (uncheck all three items) and reboot. Does the problem still occur? If not, start adding items back to msconfig one or two at a time, rebooting after each change, until the problem reappears and you'll have identified the offending process. This is clearly a time consuming procedure, but it is the best way to determine if some process loading with the system is the cause of your problem.
After you've isolated the cause, do not use msconfig to permanently disable the process. Instead, if it is a service go to START - RUN and type: services.msc (then press enter) and disable the service OR, if it a program, you can download & run a simple app such as Mike Lin's Startup Control Panel (http://www.mlin.net/StartupCPL.shtml) to enable, disable, or otherwise manage startup programs.
