Security Tool - how to remove In the future, I suggest running something like Spybot Search & Destroy's "Tea Timer" program, so you can monitor changes made to your registry.
Also, for future reference, if you press CTRL ALT DEL to open the task manager, and switch to the "processes" tab, you'll get a list of visible processes running on your computer. On the left, in the "Image Name" column, you'll see the name of the executables running on your system. With Google, you can individually search program executables up - just put in the program's name, or use a question like "What is such&such.exe". There are a lot of technical support sites that maintain lists of known executables.
Familiarize yourself with the programs in your task manager and what they do. If you pickup malware, you should be able to find the odd-one-out in your processes tab.
Oh, and here's a short pointer for crippling malware - a lot of them will be undeletable while running windows in regular mode or even safe mode. You can usually still rename the directories the files are in, making any references to them bad links. If you can find a malware's root directory, but don't have any tools or the knowledge to remove it, you can usually at least cripple it with some simple folder-name changes until you've figured out how to rid yourself of it.
