I downloaded MBAR beta yesterday and ran scan option. I have windows xp - sp3. While it went thru' scanning drivers and memory without issues, at some point MBAM disappeared from system tray. Then after some time, windows message box appeared (i don't remember the contents of the message, but it is usual one that we get when the program does not work properly), with the options :-- click OK to terminate and Cancel to Debug the program (by program i mean Malwarebytes anti-malware). After this windows itself did not respond. I had to hard boot the computer. This happened once again after restart when i ran the MBAR scan again. Please help in resolving the issue.
