This all started when my computer kept trying to run something called "help.exe'. This didn't start happening until yesterday, so I decided I would inquire about it on these forums.
I made a thread containing more info about this:
http://www.bleepingcomputer.com/forums/t/93020/straneg-things-in-my-temp-folder-helpexe/
Thanks, if anyone decides to help me out. If possible, I'd also love to know how I can find out which files carried the virus/infection/whatever onto my system.

In safe mode, on an administrative account, I used the following programs in this order, to scan my system:

Avoid clicking on other links as you don't need to try out the full install at this point, just the online scanner.

When the ActiveX Control has loaded, click on "Click here to scan".
Please be patient, as this scan may take a few hours. It all depends on the number of files on your computer.

NOTE: If you are running XP SP2, you may need to click on the Information Bar to allow the ActiveX to install and may need to repeat the BitDefender Online Scan.


When BitDefender completes the scan, select the "Detected Problems" tab.
Click on "Click here to export scan".
Save the file as an HTML to your Desktop.
Then click on the saved file and allow it to open with your browser.

Sorry I haven't responded yet.
I have been and will be working until the possibly the end of this week, and my mother and sister are usually wanting to use the computer. It's hard to find the time to do things like this. : s

But I will follow your instructions as soon as I have enough time. So keep an eye out for me in the thread list. ; P
