I've deleted the unwanted and suspicious startup entries through Spybot, as you directed.
One parting question, if you're able to guide me...do you know of a website that can guide/ teach me on how to set up a .bat file or script that can automatically run weekly scans on my computer, using some of the products you'd recommended?
This is the only way I know of to ensure ongoing good health for my computer. Otherwise, I'm afraid I do get busy and forget...
