I have had several unknown persons send PDF attachments with email
lately. I have a policy, if I dont recognise the name of the sender,
the email is deleted. however on occasion I will email a business and
will get a reply from an address not containing the business name but
from someone that works there. In that case, if I am expecting some
reply from a business, I will read the text portion of emails that
might be from such a source, and on several occasions what looked to
be spam was actually such a reply. However, unless I know the person,
no attachments are ever opened. Anyhow, I keep getting these PDF
files lately. My guess is that they are just advertising, but I wont
open them, and just delete them. My question is whether a PDF can
contain a virus or spyware? I know that .exe files, screen savers,
.zip and other compressed files can, and I have heard of a few
occasions where pictures can contain at least some sort of bad code.
I never heard anything about PDF's one way or the other.

Thanks for replies

Greg

Type "pdf virus" into Google and check the first hit.

I've gotten a few spams recently where the spam message was a page of
PDF. It was a stock scam. Apparently, the spammers are switching from
using graphics (JPEGS) to PDFs in a further attempt to get past filters.

Save the PDF file to your hard disk and scan it.

My Yahoo account has received hundreds of those attachments. Just
delete them - they are most likely advertising for stocks, medicines
and such. The PDF's are probably obfuscated so SPAM OCR engines
can't filter them out.

What's to keep you from doing an on-demand virus scan with your resident AV
product. It is more thorough than trying to establish unilaterally if "pdf's
contain viruses"
