[QUOTE=coolcolors;2765812]Ugh…well if you don’t know where your pdf is coming from then expect to get virused/malwared. It’s really simple keep your system up to date but as anything a New virus/malware is going to be missed. To think it wouldn’t be caught the day it comes out is short sightness here.[/QUOTE]
In reality, the Adobe formats like PDF are containers like a zip-file and so it does not surprise me that they are used for distributing malware.
In this respect, coolcolors has an important advice for you and so I repeat it in my reply as it is crucial to your security that you read and understand it.
