Thankfully I was not affected, but had I seen this happening, I would have shut my machine off immediately too I think. I now have the option UNchecked, just in case, although I do trust that this will never happen again. Malwarebytes is run by good people and they never meant for this to happen. I trust that it will never happen again. Unfortunately, for many people perhaps it happened while they were not physically present at their computers, and/or to hundreds of work computers with the Enterprise edition, which of course makes it all the worse, when its out of control and happening to a lot of machines... not a good scene all around. I trust that Malwarebytes will do their best to make it right, and I still trust their product and will continue to recommend it. It does make me sad to learn of what happened, especially for those who are not so tech-savvy, and those who had it happen on a lot of machines at once... that is certainly very difficult to have to deal with. I believe the whole point of the option being auto-checked is for people who don't really know what they are looking at when asked by their security software what to do with a found file. As I believe AdvancedSetup mentioned, most if not all, Anti-Virus programs have this feature auto-enabled as well. I am no computer expert by any means, but I consider myself to be an above average user (largely thanks to this forum), so I tweak the settings on my security software to fit my abilities/knowledge, but when helping someone who is not so technologically inclined, I use the auto features and trust that the products won't wreak havoc in the very unlikely event that something like this happens. I believe Kaspersky suffered an unfortunate event a few years back, and I think McAfee may as well. Malwarebytes is certainly not the first and unfortunately won't be the last, but I am confident that this is the last time this will happen for Malwarebytes.
