HJT log-Computer Freezes when Online

I am running Windows 2000 with Roadrunner connection. EZ Antivirus and EZ Firewall. Recently added 'Yahoo Toolbar'.

I have had this problem for about three months:
My computer works fine when it is off-line. When it's on-line it freezes about every hour, or so (sometimes more), usually when it's opening a program or performing some other function. Ctrl+Alt+Delete does not work. Mouse arrow does not move. Nothing. I turn it off, turn it back on, and it re-boots without any trouble.

I followed the procedure outlined in Timber's thread, "IMPORTANT! UPDATED YUCKWARE REMOVAL/HiJackThis TIPS". No problems.
Thank you, Timber.
