This is another one of the spoofed icon files that unless you have “show known file extensions enabled“, will look like a proper PDF file instead of the .exe file it really is, so making it much more likely for you to accidentally open it and be infected.

All of these emails use Social engineering tricks to persuade you to open the attachments that come with the email. Whether it is a message saying “look at this picture of me I took last night” and it appears to come from a friend or is more targeted at somebody who regularly is likely to receive PDF attachments or Word .doc attachments or any other common file that you use every day. Be very careful when unzipping them and make sure you have “show known file extensions enabled“, And then look carefully at the unzipped file. If it says .EXE then it is a problem and should not be run or opened.
