lowboat

While trying AGAIN to cancel my McAfee acct (been trying to cancel for years but they just keep billing me) a "service tech" took control of my computer and was going through parts of my computer I don't think he had any need to be in. I am now concerned that there might be a program hidden in my computer to allow him access. Will ESTET detect if this threat exists? If not do they have an option to help me determine if there actually is a threat and remove it if so?
