That is googles IP address not the one you specified earlier,
Looks like the virus already got you.
Dont mean to be awful here but If symantec and other Virus companies have already seen which site the page is being director TO I would have though the ISP would already know and suspect that there may be some wrongdoing on that page and then have shut the site down hence why you get the page not found.
IF you ever get this problem again go to
www.network-tools.com
Tick the PING section and then type in the domain name you want to find the IP addrfess.
go try it with
www.yahoo.com
