Yesterday, when I was search net by google, I get this message:

We're sorry...
... but we can't process your request right now. A computer virus or spyware application is sending us automated requests, and it appears that your computer or network has been infected.
We'll restore your access as quickly as possible, so try again soon. In the meantime, you might want to run a virus checker or spyware remover to make sure that your computer is free of viruses and other spurious software.
We apologize for the inconvenience, and hope we'll see you again on Google."

On specific word were a link to site for downloads!!!

Is anybody seen something like this before?
Is possible that someone reroute google's traffic to own site?

Sounds like they were getting large numbers of automated requests from your IP block and blocked the requests whilst they sorted it out.

well i am glad i am not the only one that gets that

i thought it was my pc

i get it after running rank checking software sometimes. maybe thats the cause

Had the same problem. I don't think the problem comes from me since I have a good routine for spyware and viruses checks.

If you software is automatically querying G it may well be in breach of their terms (and doing it with your IP and possibly sending your domain name!). If the only result is getting temporarily blocked from searching I'd count myself lucky.

It's done as a precaution to the santy perl worm that used to exploit phpbb after searching google for them. The error usually pops up during inurl: queries.

Its nothing to do with your IP, computer, infection, network.
