hijack this - can find most things running on your PC, but you'll need to find a security forum that'll tell you what's going on.

Now, is there any particular reason why you are worried about keyloggers (did your friend actually get one or lose info another way)?  You're more likely to click on a fake email asking for your information IMO.  Some people also install keyloggers (electronic and physical ones) on their spouse's / GF's / kids' machines if there are trust issues going on.  There are also other things like using popular passwords, brute force programs, etc to break in and get info.  Or you could be the NCsoft site which has a bug where you can sometimes see another person's account when you log in.

WARK!
