Tor (panda)

After using Tor for a few months I've only recently been getting these errors: On google search I sometimes get this msg:

"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.
If you're continually receiving this error, you may be able to resolve the problem by deleting your Google cookie and revisiting Google. For browser-specific instructions, please consult your browser's online support center.
If your entire network is affected, more information is available in the Google Web Search Help Center.
We apologize for the inconvenience, and hope we'll see you again on Google. "
Any suggestions? Do any of you (who use Tor) get this?
Also getting errors when trying to make Journals that say's "» You do not have the correct confirmation code. You are not authorized to add a journal"

thanks in advance!
