Ryan, thanks for your log. Nothing really "pops out" at me in the log. You said that the problems you were having were....Internet Explorer 7 working either very slowly or not responding
even sometimes, not responding during the cookie.
I am not certain what you mean by that... and also this
I have tried using Spydoctor software, but during the scan, my computer automatically run in OS window and warning that problems has happened
What do you mean by OS window?

After you completed the steps in the link I gave you there should also have been a log generated by the AVG Anti-spyware program. Could I see that also please.
Judy
