Viruses in PDF files?

1
Do you think it's possible ? I've read PDFs can have code that access anywhete on the interweb
thus it could download almost anything and run it or even have some viruses embedded in the PDF !

a quote :
"Yes, Adobe PDF documents can carry various types of viruses or malicious executable code. Malware is primarily hidden in multimedia content, hyperlinks, JavaScript code, and system commands. The malware attack executes when users open the file or interact with the embedded content after opening."

thanks

Yes DOCX can have "Worm" scripts. There are more infected DOCX files than PDF's.
The thing is .doc and .xls extensions have not been the default extension since Office 2007 so .DOCX is now taking over.

Do you have any concerns or certain files from some sites that you are worried about?

I'm not afraid of some particular file, just to be careful with possible hidden malware. I didn't know there could be some in PDFs

I don't think you could add a virus/trojan to a EX4 or even EX5 format indicator or EA. I don't think it's possible at all
with a DLL ok, but if not I don't see how

I do not download closed-source indicators ... at least so that there will be no problems in the updated versions of the terminal in the future. I know of a case when a program with automatic sending of screenshots was installed along with the indicator.

It can easily be understood. Any indicator can send many various notifications
and information regarding the trading accounts in which it operates. This option
can simply be hidden (as it's external for many indicators used), and the third-party
e-mail / phone number can be involved. Apart from this, any compiled file can stop
to work for the next version of MT4, or MetaCompany can stop to support MT4,
or one will want to use other platform than MT4, etc.
