403 Forbidden from Google ?

I just found this today, that the translation button on this page .. can not be used anymore and that’s why i decided to remove it :(

I do not know the reason why the Google translation service reject request from this site, because previously it just works fine without problem .. but now ? i always get this message no matter which translation button i press .. and it shows the same message too eventhough i'm using proxy to connect to my host

We're sorry...

... but your query looks similar to automated requests from a computer virus or spyware application. To protect our users, we can't process your request right now.

We'll restore your access as quickly as possible, so try again soon. In the meantime, if you suspect that your computer or network has been infected, you might want to run a virus checker or spyware remover to make sure that your systems are free of viruses and other spurious software.

We apologize for the inconvenience, and hope we'll see you again on Google.

Now .. i'm sure that my site doenst distribute malicious file or something bad like that but how come this is happening on this domain but works on other site that use the same technique like this site too ? (as a side note, i’ve already changed the user agent several times but still no luck)

I guess Google just does not like their translation tool being used on this domain :(

Update : I found that Google only allow, several request made in 24 hours. So the only way to fix this is .. i have to wait for another 24 hours before Google allow me to use their translation service once again :(
