Hello, I've written an article which should allow you to find out if your computer is infected, even if it's infected with malware that no vendor has yet seen. It's called How to Know If Your Computer Is Infected. Please check it out and let me know what you think. Note that I am aware that you could scan with a few programs and be relatively sure that your computer was infected, but I wanted to come up with a method that was nearly 100%. (Note that I did use the word nearly ) I'd welcome any comments or criticisms you have. Thanks.
