Not sure what to call this (see screenshots)malware? I was in Yahoo! mail and opened up an order confirmation for an Amazon order. This popped up. After taking some screenshots, I force-quitted Chrome (version 11.0.696.71). The email opened up fine the next time around. Anyone have idea how this cropped up? I don't do illicit stuff on my Mac (see sig), such as torrenting, going to untrustworthy sites, etc. and since it seems to be web-based, it just may be a problem within the mail client. However, if anyone has a slightly better clue about what's going on, I'd love some tips . Thanks!
