All of our users are receiving the 403 Forbidden message when trying to search Google. I pinned it down to one user who was infected with some sort of trojan that runs a proxy server - called asprox. I cleaned the trojan and have run all types of spyware removal and AV software, but I am still getting the same error from Google.
When I turn off this user's computer, or disconnect his network cable, the error messages from Google go away. When I bring back this user, the messages start again. But I can't seem to figure out what is still running on his machine.
I have attached a logfile from Hijackthis. He is running Windows XP Pro.
