Virus Help

[Phantom_RAcast]

I was searching on google, and the second I clicked a link auto protect came up and said a virus was detected, it said it couldnt fix the problem, so I do a system scan and it doesnt come up, so I look for more info on nortons site, and I look for trace of it on my system but I can find no evidence of it, so I'm wondering if it hid itself somehow or if its a fluke or something, heres the nortons info link http://securityresponse.symantec.com/avc...avadd.html now not only am I pissed that the wrong site came up but now I have to worry about being infected >:l, any help is aprreciated
