Weird symptoms - not right.

[crash-dadio]

My nephew left town 4 weeks ago and since, my computer no longer recognizes my external hard drive, takes longer to open web pages in firefox and disabled my ability to update Ad-aware - erroring each time I tried. I un-installed and reinstalled twice. No good. AVG says all is well. I use this computer for business now and need to find out what is up. I also tried to run my expired (webroot) Spysweeper - no good. I accessed my external hard drive from my other computer and found almost twenty GB of music, porn and video clips of all kinds that he stayed up all night downloading with Limewire before using up all my blank CD's.
I am pasting my hijack this log below. I would greatly appreciate someone helping make some sense of this and guiding my clean up. Thank you.
Oh Yeah. I wiped the hard drive with Eraser. This should be good to use again, shouldn't it?

Welcome to Safer Networking, I wish to be sure you have viewed and understand this information.
"BEFORE you POST" (READ this Procedure before Requesting Assistance)
http://forums.spybot.info/showthread.php?t=288
All advice given is taken at your own risk.
Please make sure you have read this information so we are on the same page.

I try not to read what folks say first so I don't get biased, I am not seeing much in the log but trash. Then I read you formatted. We require a Kaspersky Online Scan, post one and I'll clean your log up and get you on your way.

Run this online scan using Internet Explorer:
Kaspersky Online Scanner from http://www.kaspersky.com/virusscanner

Next Click on Launch Kaspersky Online Scanner

You will be prompted to install an ActiveX component from Kaspersky, Click Yes.

* The program will launch and then begin downloading the latest definition files:
* Once the files have been downloaded click on NEXT
* Now click on Scan Settings
* In the scan settings make that the following are selected:
* Scan using the following Anti-Virus database:
* Standard
* Scan Options:
* Scan Archives
* Scan Mail Bases
* Click OK
* Now under select a target to scan:
* Select My Computer
* This will program will start and scan your system.
* The scan will take a while so be patient and let it run.
* Once the scan is complete it will display if your system has been infected.
* Now click on the Save as Text button:
* Save the file to your desktop.

Then post it here. (no need to post a clean scan)

Thanks...Phil
