Hi, I'm not sure if I have a virus or not but I can't run malwarebytes free. I download it and immediately get runtime error 0 and runtime error 440. I've tried the majority of the solutions detailed on this subject in your forum bur without any suucess.
I'm running on windows XP SP3 with AVG free and zonealarm. AVG, ESET and Kaspersky don't show any viruses.
