Internet Explorer & Firefox are Very Slow & "Not Responding

This just happened recently. The internet has been slow and alot of the time when loading something online it will "Not Respond" and freeze for a couple seconds. It's getting annoying and im afraid that it will eventually crash my computer.

I've already tried Disk De-fragmenting it as much as I can.
I have AVG anti-virus
and still have alot of memory.

Any tips at all would be nice. Thanks!

Download OTL by OldTimer to your Desktop.

• Close all windows and double click OTL.exe
  
• Click Run Scan and let the program run uninterrupted
  
• It will produce two logs for you, one will pop up - OTL.txt, the other will be saved on your Desktop - Extras.txt. Post both logs in this thread.
  
• You may need to use two posts to get it all.
