My system got infected with pspv.exe.I somehow deleted but it appears and disappears in oobe folder so i cannot delete now. Does anybody have idea on how to clean pspv.exe from system.
Other issue i have is after system rebooting i see only blank screen so i need to run explorer from task manager. So what is that missing here.
Please let me know if i am not clear on my question.
