Before you open a PDF attachment from an anonymous ET poster: http://www.trustedsource.org/blog/153/Rise-Of-The-PDF-Exploits. I see a fair amount of Excel, Word and PDF attachments being posted or linked to here from time to time. I hope no one is reading them from their trading computer...
A "friend" sent me some PDF articles on trading. My Avast detected trojans inside! Trash bin they go... they won't get a chance to reach my Adobe.
So, what should we do? How do we read the attachments? Many of them are useful information which we need.
i think dont click on them, right click on them and save to disk, scan with virusscanner, then read if clean
Most virus scanners will scan for malware any time a file is accessed so the extra steps you are doing (manually saving to disk and then scanning) should not be necessary.
