No it's not. It's on your system!
Work through the suggestions in the "Helping yourself" sticky in the Security forum section, and then post a topic in there if you have remaining problems. MacAffee Virus Shield by itself doesn't detect all intrusions, I'm afraid, and it sounds like you've collected some malware from browsing. I can assure you it never came from here :D

Also, if you're browsing through our Security forum, some HJT logs are detected as containing malicious scripts sometimes, as the text will have URLs embedded in them.
If McAfee will allow you to proceed, then it's cool, and the messages can be disregarded if you've performed Catweazle's suggestions.
