Hello. Malwarebytes will remove a trojan from my computer but the same exact thing keeps coming back every scan. It always seems to reappear right after it is deleted. Another problem I am having is that my browser unexpectedly closes and this has happened numerous times. I'm not really sure what is going on. I would appreciate any help. Thanks in advance.
