Symantec A/V log parser

I was culling through the logs on one of my systems the other day and realized that I was getting a fair amount of alerts from my Symantec A/V servers. At first, I was not interested in what malware was being detected and cleaned but it got me thinking about what interesting patterns existed. I suspected that the majority of malware infections were caused by a minority of users as most malware these days require some user action. To test this theory I wrote a simple parser
to convert the logs to something that I could push into a visualizer and started looking for interesting patterns.

Here is a histogram and a heatmap of several months of data.
