Hi ladybugsy,
First thing I notice, which will MOST d
efinitely cause your my pc isn't performing like it should
...and also....
freezing up
is you are running two antivirus programs...AVG8 and at least a portion of symantec corporate edition. This is an ABSOLUTE NO-NO. Uninstall one of them. If the Symantec is up to date, not ready to expire then keep it. If NOT...UNINSTALL IT. Having two antivirus programs will not only really decrease performance it also lessens your protection because the two end up competing with each other and allow the nasty items in.

What is your Hard drive size and how much space is remaining? How much RAM do you have installed?
Please delete this old version of HiJackThis and download the NEW VERSION
Then I would like for you to generate and Uninstall list using HJT.
To do this do the following;
To access the Uninstall Manager you would do the following:

  1. Start HijackThis
  2. Click on the Config button
  3. Click on the Misc Tools button
  4. Click on the Open Uninstall Manager button.

You will now be presented with a list of programs installed on the computer.
Click on the Save list... button and specify where you would like to save this file. When you press Save button a notepad will open with the contents of that file, save it as a .txt file to your desktop so that you can find it easily.
Post back here with that list.
