Patch your Google Chrome –
From cve.mitre.org
Why would a Google Chrome vulnerability be important? because if you happen to bump into a nefarious website
(unbeknown to you) it will affect your Google Chrome and then little by little the hacker will gain more information.
Pretty soon there will be open ports that you may not know about and those ports are “phoning home” to the master.
Scan your systems(with A or Σ) to see if you have rogue applications on your systems.
