I want to download a crochet pattern from the internet but after I've gone through the process of registering as a member and clicked on Download, I got a warning:
"This type of file can harm your computer. Do you want to keep FC01109.pdf anyway?"

If it's harmful, why am I given the option to download it?

with a suffix of .pdf it should be OK pdf ( Portable document format file ) is a adobe document which is so secure it can be used as court evidence . This file will be your pattern , save it and you can keep referring back to it .

It will use adobe acrobat reader to open it .

I suspect what you are seeing is a generic warning. Just about anything you download from the internet has the potential to cause problems. Hence the message. It doesn't necessarily mean that that specific file is harmful.

All it is really saying is "be careful". If you are sure the source of the file is trustworthy and have good anti virus protection then most of the time you should be OK to ignore the message.

I have had Microsoft Windows/Internet Explorer throw up that message when downloading files from the Microsoft website. So if Microsoft don't even trust their own files to be safe who do they trust??

What antivirus software are you using?

Not necessarily. Firefox and Chrome have their own built-in PDF readers, and the OP might have some other PDF reader installed.

Not so, malware can be embedded in PDFs, and PDF readers do have security flaws (and there is no such thing as a file format that can be used as court evidence - unless you accept that all file formats can be used as court evidence*). So the message "PDFs are safe" is just wrong.

What's more important is:

- is the source website reliable, any indications that it is a scam (being offered free stuff?)
- is the format an expected type? pdf for general documents is quite normal, executables less so.
- in the case of pdfs, is your reader up to date?

*Perhaps what you are referring to is a court requiring that electronic documents be filed as PDFs. This may well be the case but has nothing to do with security and everything to do with widespread compatibility.

It seems to be a legitimate website - free patterns but they're pushing their lessons, yarns, etc. very hard.

I downloaded two patterns and am re-running system scan with Avira. No problem so far........................
