Most online poker sites that are decent, won't allow 'cheating' types of software. Chances are you'd be picked up ASAP, account locked and investigated for fraud. Failing that you can try party poker, the site is too easy to rip off
No, thats not cheating but usually that kind of software is not worth trusting. Most decent online poker sites will have a tool in the cashier or software that can tell you an update version. Failing that just contact the poker helplines, try going onto google.
But then give it a week, after you have lost more than you can afford and your be claiming its all a fix
