Smany "advices". I have the same error, I don't ever used any kinda hack/cheat program so that error must be a conflit between the Xtrap and another process ocurring.
In my case I just keep trying till I "pass" that error (usually at second attempt I login).
About the svhost.exe if I'm not wrong that process is connected with your antivirus or microsoft security. THAT'S NOT A VIRUS! duh
