Google redirect malware?

Hi everyone,

Since last night, I’ve been getting the following message whenever I try to visit Google.com:

  1. That’s an error.
    The requested URL /cgi-bin/redirect.ha was not found on this server. That’s all we know.

And in my URL box, there is an extra “/cgi-bin/redirect.ha” behind the normal Google URL. Is this some kind of redirect trojan? How do I remove this? Any advice is greatly appreciated. Thanks a lot!
