Have been using Malwarebytes free version for years and have been thoroughly satisfied with it. However, recently I have been getting an error message on trying to start a scan: 'Malwarebytes has stopped working - Windows will close the program and notify you if we find a solution...' After days of getting this message repeated, I assumed it may be connected to my new AV (Bit Defender) clashing with the free version. So...valuing Malwarebytes as highly as I do, I bit the bullet and ordered the Premium version. You know what's coming next:- the problem is still there!!! I have tried deactivating Bit Defender whilst Malwarebytes attempts to scan but no change. Help please!
