i use MalwareBytes Pro and now just a few minutes ago i got in my email inbox a free licence for IObit Security Pro 360
I voted Superantispyware for my top choice but actually Malwarebytes carries equal weight with me but you could only vote for 1.
Windows Vista: Malwarebytes' Anti-Malware alongside MSE and Threatfire Windows 7 x64: Malwarebytes' Anti-Malware alongside Avast Home and Comodo
Well since Prevx can not be used as ondemand, it can be hardly a choise. It silently installs and then runs in backround forever, until it is uninstalled I don understand the condition, "those with no removal ignored". You have to know, that you are infected, then it is easy to find a way to remove it. MWAV.
