I have had a problem for months on my laptop...Malwarebytes Anti-malware would suddenly crash, because it had automatically downloaded a corrupted definition file. I assumed it was a Malwarebytes issue. Then I started noticing programs and drivers I had downloaded from other websites wouldn't execute, so Malwarebytes was not the problem. My desktop ran Malwarebytes with no problems, but I was still on ZA 9. Once I updated my desktop to ZA 10, the problem started there as well. The way to fix it is to close ZAISS, donload the update, then re-start ZAISS.

There is only one possible conclusion...Once ZA is running, it is fine for a period of time...then it starts corrupting downloads. I tried it with Browser security off and it still happened. This is a problem with the core program and it happened on two different machines.
