I downloaded the latest free version 2 with no trouble. It required a re-boot and did a scan when re-booted. I have been using this program along with my paid for program for years and it is very reliable. I use the add-on Chameleon for this to work safely without being hacked it must be put into the same folder as Malwarebytes. I dont have any trouble with it or other protection programs as apart from my paid one none are run in real time but only on demand. Its the one hackers fear as a high tech. Hacker tried to disable it but couldnt so caused my PC to switch off. I wouldnt be without it.
