Database optimizations tonight.

14 October 2012 - 08:57 PM

We are optimizing the database tonight. The only thing you should notice is that the database will be smaller and your scan times may be a little quicker, but it wont be dramatic.

Small test #2

18 July 2012 - 03:14 PM

As with the last test please do not reply. I will use this thread to document changes in detection to a serious threat over time.

In this case I will be posting gen 1 and gen 2 of the same threat from the same source. I will include further generations as they are generated.


First gen 1. At this moment this sample is a day old and already obsolete.

Database optimization today 7/18/2012.

18 July 2012 - 06:07 AM

We will be optimizing the Malwarebytes database later today. You do not need to do anything, the optimized database will arrive in an update.

Other than a smaller total size and slightly faster scan times you should see no other changes.

Running a small test

15 July 2012 - 10:09 PM

Please do not comment on this thread. I am only posting here to give points of reference over time on detection of a 0day sample.
