Hi, A friend asked me to clean his Vista PC. I installed Malwarebytes and at Heuristic Analysis it found multiple problems, mostly popups. I quarantined them and then deleted them all. Then I repeated the scan and it found exactly the same problems. I repeated it 2 more times and the same infections came up. How is it such a trusted tool failed to quarantine/delete infections......? I tried to re-install it but it did not help. I have been using Malwarebytes on many computers for many years without any issues. Thanks, BBDS
