email@example.com and McAfee
Posted on 2016-09-14
Our documents got infected with the firstname.lastname@example.org. It encrypted thousands of files. Fortunately I back up everything, so I was able to put backups in place. But my question is why didn't our Virus protections, Spyware blockers, etc., catch this. I understand from research that this normally comes in as ads or malware, but my Manager tends to think that even if this came in through email, that our protections should have stopped it at the source and not spread throughout our entire system. It only affected files that everyone had write access to.
I need to prevent this from happening. Other than totally locking down the internet what else can I do. I have anti-virus software in place, Barracuda Spyware device, as well as Malware software. I know the rules of prevention but I need to know if there is anything that can stop it if it hits our systems again.
