Need help :(

I have a terrible virus - my operating system is Windows XP. The virus I have makes popups like adultfriendfinder, another porn-ish one, and one for some other product pop up when I connect to the internet. recently it seems like every time I turn on the computer, something else goes wrong with it. Now when I log onto my account (I'm on my dad's right now), I can't even connect to the internet because the "connect to..." tab on the start panel disappeared. I try to double click on 'dsl connection' on my desktop but nothing happens. i have done most of the things that I was supposed to do according to the "read this before you post and do all these things before you ask for help" or whatever. some of the stuff, like the panda scanner, wouldn't even work for me. When I minimize windows on any account on the computer, the windows don't even go to the start tab. they hover behind it or above it. The "search" function on my computer doesn't work. I have been running Ad-Aware, ewido and spybot excessively with no results. I don't know what to do - I have countless documents saved on this computer and I am afraid I'm going to have to get everything erased off the motherboard and start over - what can I do? hellp pleeeease.

 

If you have completed the READ ME, attach a current HJT log with the logs from the two online scans.

 

Edit by bjgarrick: Inline log attached!

here is the HJT log. i just tried to do the two online scans, and neither of them worked. I can't click on links right now, so I have to type in the properties of each link into the address tab on internet explorer - when I tried to do that for the Bitdefender scan, it wouldn't let me access the scan. and Panda has never worked on my comptuer.

 

Download the following two files, create a folder on your desktop, call it TSC. Save these 2 files there.

Note: They must be in the same directory for it to work properly!

Sysclean Package

Pattern.zip

After you complete the above, locate the file "lpt201.zip", right click to extract the contents to the same directory.

Once you complete the steps above, REBOOT INTO SAFE MODE!

Once in Safe Mode double click the file sysclean.com. When the system cleaner loads, click SCAN to start the scanner. After you complete the scan reboot and ATTACH a fresh HJT log along with the Trend SysClean Log.
