This week, Adobe announced a new Security Update and said that they were going to go on a cycle of releasing upgrades on a 3 month cycle, similar to the dates that Microsoft uses for their monthly security patches.

Adobe reiterated that users must look to anti-virus programs for protection.

Obviously, it is common to receive pdf files. What isn’t well understood is that withing the file there can be executable code. That would be fine if it were only multimedia files. But hackers have figured out how to put trojans and viruses into the pdf…which can execute as you read.
