Google reacted in a prompt matter to the fix the problem. This is a risk that will always exist when a software becomes open source and you are downloading third party programs - which the Android Market clearly warns you of this risk before downloading the applications. I personally am not holding Google accountable for this incident and am pleased with the quick remedy to the issue.
Although I do find it ironic that Google fixed the problem by using a backdoor 'kill switch' in the android software to fix the backdoor malware of infected users.
