This is very useful application to check on your computer if there is any keylogger or other suspicious software who steal information or send to other computer cia internet. Is good to keep it active to prevent trojans installations.
Personal, i use antivirus software like Nod32 or McAfee antivirus to protect in real-time. If other people have access to my PC, i run Zemana AntiLogger to check it.This is useful because keylogger are hidden and are not visible in system files.
