I've been Phished!

Im extremely careful when it comes to junk mail, phishing, pop ups, and spyware schemes. But 2 days ago, I fell for a real sneaky phishing scam. I was talking to a coworker on AIM and suddenly he sends me this URL. I click on it and the yahoo photos page loads. I thought he wanted me to check out some pictures hosted on his yahoo photos account and in order to view the photos, I would need to sign into my yahoo account to view the pics. I was totally not thinking and I just went ahead and logged in. Lucky I used my dummy yahoo account. Phew. Well basically, this dummy yahoo photos page is a fake copied page that is hosted on a free geosities website. So basically, they just basically know my login and password. I cant believe I fell for it. But the reason I fell for it is because i didnt know that spyware that was on my coworkers machine can send out these bad IM's to people. Yowsers. This one was real tricky. More details on the yahoo photos phishing scam.
