So after weeks w/out probs, this has started to randomly happen again on one of our machines. No rhyme or reason to when this occurs. We have followed the instructions, reinstalled AC (it is a client machine), and then out of the blue MS essentials detects threats and AC configuration message pops up with every click. This is hard to troubleshoot b/c of the irregularity, and frustrating because we feel we are just doing the same clean-up over and over; no problems for a few days or weeks then it all starts again. Anyone else having this type of problem?
