Hello,
We have been made aware that when BullGuard and Malwarebytes are installed alongside each-other, a system crash can occur (blue screen of death).
Upon investigating this issue with Malwarebytes we have discovered that the problem only occurs in this very specific case where Windows, Malwarebytes and BullGuard are not updated to their latest versions.
We advise customers which encounter this issue to update their Windows, BullGuard and Malwarebytes manually.
Then, very important, reboot the computer, to ensure the system loads with the updated software.
